Abstract

In order to form safety markings at a planar card made of a plastics material, which card may be used, for instance, as credit card, this card is built up from at least two parts. The inner border area between these two parts comprises a relief-like structure which is the carrier of the safety marking. In order to generate a watermark-like effect the upper part is made of a opaque plastic material and the other part is made of a transparent plastics material. When viewing through this card the areas of the opaque layer having the largest thickness appear as darker areas, whereby when viewing the same way the areas having a smaller thickness show a certain brightness. After being embossed the two parts of the thermoplastic material are joined to each other such that they cannot be separated such that no access from the outside is possible to this safety marking. Accordingly, an additional safety factor is arrived at in cards which can be used as money substrate, identification means or a license for any kind of access.

Description

Die Erfindung betrifft eine ebene Karte aus thermoplastischem Kunststoff mit visuell wahrnehmbarem Sicherheitszeichen, sowie ein Verfahren zu deren Herstellung.The invention relates to a flat card made of thermoplastic material with a visually perceptible security symbol, and a method for its production.

In neuerer Zeit haben bedruckte Karten aus Kunststoff weite Verbreitung als Kredit-, Geldsubstrat- und Ausweiskarten gefunden, welche eine Dienstleistung vermitteln, einen Wert repräsentieren oder ein Zutrittsrecht beinhalten. Die den Träger identifizierende Teilinformation sowie die Merkmale, welche die Karte einer bestimmten Organisation oder einem System zuordnen, sind in Form von Aufdrucken,Prägungen, Stanzungen oder Magnet-, Laser- oder holographischer Information auf der Karte angeordnet. Dabei ist es nun relativ einfach, die äussere Erscheinung solcher Karten nachzubilden. Es ist einleuchtend, dass damit die Möglichkeit des Missbrauchs solcher Karten, welche mehr und mehr den Bargeldverkehr ersetzen, besteht, ohne dass hierfür ein allzu grosser Aufwand nötig ist. Dabei hat insbesondere das Publikum keine Möglichkeit, sich von der Echtheit einer solchen Karte zu überzeugen.Recently, printed cards made of plastic have found widespread use as credit, money substrate and identification cards which convey a service, represent a value or contain an access right. The partial information identifying the carrier and the features which assign the card to a specific organization or system are arranged on the card in the form of imprints, embossings, die-cuts or magnetic, laser or holographic information. It is now relatively easy to recreate the appearance of such cards. It is obvious that there is the possibility of misusing such cards, which are increasingly replacing cash transactions, without requiring too much effort. The public in particular has no way of convincing themselves of the authenticity of such a card.

Es sind deshalb bereits Karten bekannt, die als Verbundkarten ausgestaltet sind, wobei eine Papierschicht zwischen zwei Kunststoffschichten eingeschlossen ist. Die Papierschicht ist mittels einem von den Banknoten her bekannten Sicherheitsdruck versehen und weist, ebenfalls wie die Banknoten, ein Wasserzeichen auf, das in der Durchsicht erscheint. Ferner können auch Teile der Kunststoffoberflächen mit einem Druckmuster versehen sein.There are therefore already cards known as V erbundkarten are configured, wherein a paper layer between two plastic layers included. The paper layer is provided by means of a security print known from the banknotes and, like the banknotes, has a watermark which appears in the review. Furthermore, parts of the plastic surfaces can also be provided with a print pattern.

Derartige Karten bieten zwar erhöhte Sicherheit, weisen aber mehrere Unzukömmlichkeiten auf. Infolge des Verbundes unterschiedlicher Materialien, wie Papier und Kunststoff, wird durch die Prägungen der fertigen Karte erfahrungsgemäss eine Deformation hervorgerufen. Die Karte erhält durch die auftretende Spannung eine Wölbung in Prägerichtung, welche die automatische Lesbarkeit der eingangs.genannten Informationen beeinträchtigt, sofern solche darauf vorgesehen sind. Ferner bietet der Aufbau der bekannten Karte die Möglichkeit zu unerwünschten Eingriffen. So kann etwa die Karte entlang der Papierschicht aufgetrennt werden, was Manipulationen an dieser Papierschicht ermöglicht, oder es können mittels eines Lösungsmittels die schützenden Kunststoffschichten gelöst werden, so dass die Papierschicht danach offen liegt. Aus solchen Erwägungen ist es grundsätzlich unerwünscht, dass derartige Karten aus einem Papier-Kunststoffverbund bestehen. Vielmehr ist es erwünscht, Vollkunststoffkarten zu schaffen, die die nötigen Sicherheitseigenschaften aufweisen. Da solche Karten ebene Oberflächen aufweisen müssen, ist jedoch bisher keine Ausgestaltung bekannt geworden, welche Sicherheitsmerkmale aufweist, wie sie etwa von neueren Banknoten bekannt sind, indem diese oft unebene Oberflächenstrukturen voraussetzen. Ferner sind bei Vollkunststoffkarten keine Durchsichtsmerkmale bekannt geworden.Although such cards offer increased security, they have several inadmissibilities. As a result of the combination of different materials, such as paper and plastic, experience has shown that the embossing of the finished card causes a deformation. The card is given a curvature in the embossing direction due to the tension that occurs, which impairs the automatic readability of the information mentioned at the outset, provided that it is provided thereon. Furthermore, the structure of the known card offers the possibility of unwanted interventions. For example, the card can be separated along the paper layer, which enables manipulation of this paper layer, or the protective plastic layers can be removed using a solvent, so that the paper layer is then exposed. From such considerations, it is fundamentally undesirable for cards of this type to consist of a paper / plastic composite. Rather, it is desirable to create all-plastic cards that have the necessary security properties. Since such cards must have flat surfaces, however, no configuration has hitherto become known which has security features such as are known, for example, from newer banknotes, in that these often require uneven surface structures. Furthermore, no transparency features have become known for all-plastic cards.

Hier will die Erfindung Abhilfe schaffen.Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Karte zu schaffen, welche visuell erkennbare Sicherheitsmerkmale aufweist, die in der Karte unzugänglich eingeschlossen sind.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a card which has visually recognizable security features which are enclosed inaccessibly in the card.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass. die Sicherheitsmerkmale von aussen visuell erkennbar sind, jedoch unzugänglich sind, indem sie von einem durchsichtigen Deckkartenteil überdeckt sind, welcher untrennbar mit dem die Merkmale tragenden Kartenteil einstückig verbunden ist, derart, dass die Merkmale zwecks Manipulationen von aussen unzugänglich sind.The advantages achieved by the invention are essentially to be seen in the fact that the security features are visually recognizable from the outside, but are inaccessible by being covered by a transparent cover card part which is inseparably connected to the card part carrying the features in such a way that that the features are inaccessible for manipulation from the outside.

Dabei sind insbesondere zwei bevorzugte Ausführungsarten zu erwähnen. Bei der einen ist das Sicherheitszeichen vorzugsweise in Durchsicht wahrnehmbar, indem der eine der beiden Teile aus opakem, der andere aus transparentem thermoplastischem Kunststoff besteht, wobei die reliefartige Struktur derart verläuft, dass in bestimmten, ein Sicherheitszeichen definierenden Bereichen der opake Teil eine örtlich unterschiedliche Dicke aufweist. Bei der anderen Ausführungsform ist das Sicherheitszeichen vorzugsweise in Aufsicht bei geeignetem Betrachtungswinkel wahrnehmbar, indem mindestens ein Bereich der reliefartigen Struktur der inneren Grenzfläche eine strichrasterartige Wellenform aufweist, wobei diese Grenzfläche derart mit einem Druckmuster versehen ist, dass sich dessen visuelle Erscheinung mit änderndem Betrachtungswinkel verändert.Two preferred embodiments should be mentioned in particular. In the case of one, the safety sign is preferably perceptible by looking through, in that one of the two parts consists of opaque, the other of transparent thermoplastic, the relief-like structure being such that in certain areas defining a safety sign the opaque part has a locally different thickness having. In the other embodiment, the safety sign is preferably perceptible from above at a suitable viewing angle, in that at least a region of the relief-like structure of the inner boundary surface has a dash-like waveform, this boundary surface being provided with a print pattern such that its visual appearance changes with a changing viewing angle.

Obschon nachfolgend die bereits erwähnten unterschiedlichen Ausführungsarten, von denen sich die eine auf Durchsichtskennzeichnung, die andere auf Draufsichtskennzeichnung bezieht, der Klarheit halber einzeln dargestellt werden, sei gleich zu Beginn erwähnt, dass beide Ausführungsarten mit Vorteil kombiniert werden können, wie dies etwa in Fig. 5 schematisch angedeutet ist.Although the different embodiments mentioned above, one of which relates to see-through labeling and the other to top view labeling, are shown individually for the sake of clarity, it should be mentioned right from the start that both embodiments can advantageously be combined, as is shown in FIG. 5 is indicated schematically.

Zunächst werden Ausführungen beschrieben, welche die Durchsichtskennzeichnung erlauben. In Fig. 1 ist ein Abschnitt einer solchen erfindungsgemässen Karte 1 in senkrechter Aufsicht dargestellt, wobei man sich hinter der Karte eine Lichtquelle vorzustellen hat. Dabei treten zwei Zonen, die stufenlos ineinander übergehen können, aus dem übrigen Helligkeitsbild hervor. Eine dunkle Zone 4 und eine diese begrenzende helle Zone 5. Dies entspricht dem Erscheinungsbild des herkömmlichen Wasserzeichens auf Papier, welches durch die Konzentration von Papierfasern an bestimmten Stellen erzeugt wird, während an umgebenden Stellen Fasern abgezogen werden, was die begrenzenden hellen Zonen erzeugt. Die unterschiedlichen Faserkonzentrationen führen zu einer unterschiedlichen Lichtdurchlässigkeit, welche Ursache für den beschriebenen Effekt ist. Bei der erfindungsgemässen Karte, die keine Papiereinlage aufweisen soll, sondern vollständig aus thermoplastischem Kunststoff aufgebaut ist, kann das erwähnte Wasserzeichen nicht auf die beschriebene Art erzeugt werden. Hierzu wird vielmehr, wie aus Fig. 2a und b ersichtlich, eine Karte aus zwei Halbteilen 2,3 aufgebaut. Der eine Halbteil 2 ist aus transparentem Kunststoff, der andere Halbteil 3 aus opakem, d.h. durchscheinendem, trübem Kunststoff. Solches Material weist einen erhöhten Lichtabsorptionskoeffizienten β auf, so dass das Licht bereits beim Durchgang einer relativ dünnen Schicht von z.B. 0.4 mm merklich abgeschwächt wird. Man macht sich nun den Umstand zu Nutze, dass die Lichtabsorption von der durchlaufenden Wegstrecke abhängt, nach dem Gesetz;

Figure imgb0001

  • wobei I : einfallende Lichtintensität o
  • I : Lichtintensität nach der Wegstrecke S
  • ß : Lichtabsorptionskoeffizient
First of all, versions are described which allow the transparent marking. In Fig. 1, a section of such a card 1 according to the invention is shown in vertical supervision, one having to imagine a light source behind the card. Two zones, which can merge seamlessly into each other, emerge from the rest of the brightness image. A dark zone 4 and a light zone delimiting it. This corresponds to the appearance of the conventional watermark on paper, which is produced by the concentration of paper fibers at certain points, while fibers are drawn off at surrounding points, which creates the delimiting light zones. The different fiber concentrations lead to a different light transmission, which is the cause of the described effect. In the card according to the invention, which is not supposed to have a paper insert but is constructed entirely from thermoplastic, the aforementioned watermark cannot be produced in the manner described. Rather, as can be seen from FIGS. 2a and b, a card is constructed from two half parts 2, 3. The one half Part 2 is made of transparent plastic, the other half part 3 of opaque, ie translucent, cloudy plastic. Such material has an increased light absorption coefficient β, so that the light is noticeably weakened when it passes through a relatively thin layer of, for example, 0.4 mm. One now takes advantage of the fact that the light absorption depends on the distance traveled, according to the law;
Figure imgb0001
  • where I: incident light intensity o
  • I: light intensity after the distance S
  • ß: light absorption coefficient

Eine grössere Schichtdicke führt demnach zu einer grösseren Lichtabsoption. Der Einfluss des transparenten Halbteils 2 kann hierbei ausser Acht bleiben, da sein Lichtabsorptionskoeffizient B im Vergleich mit demjenigen der opaken Schicht vernachlässigbar klein ist. Der opake Halbteil 3 wird nun derart ausgebildet, dass zur Bildung eines wasserzeichenähnlichen Effekts Bereiche 4 erhöhter Dicke entstehen. In benachbarten Bereichen 5 dagegen entstehen Zonen geringerer Dicke, so dass in der Durchsicht um die dunkel erscheinenden Bereiche hellere Bereiche 5 entstehen, wie es für das Erscheinungsbild herkömmlicher Wasserzeichen kennzeichnend ist. In Fig. 2b ist dies schematisch durch Pfeile angedeutet, die einerseits das gleichmässig einfallende Licht und andererseits das durchtretende Licht darstellen, wobei die Dicke der Pfeile der Lichtintensität entspricht. Die Prägung des Reliefs im opaken Halbteil 3 erfolgt derart, dass die gesamte Materialmenge konstant bleibt und nur eine Materialmengenverschiebung aus den Bereichen 5 in die Bereiche 4 stattfindet. Dies bedeutet, dass die mittlere Dicke über die mit einer Reliefstruktur versehenen Bereiche 4 und 5 gleich der Dicke der restlichen Karte ist. Die Abformung erfolgt mit einer Prägeform bekannter Art. Der transparente Halbteil 2 wird mit einer entsprechenden, gegengleichen Prägung versehen, wobei die herzu verwendete Prägeform vorzugsweise von der ersten Prägeform elektrolytisch abgeformt ist. Die beiden Halbteile werden dann durch Laminage untrennbar zu einem einzigen Teil homogen zusammengeformt. Entlang der mit der Reliefstruktur versehenen Grenzfläche der beiden Halbteile findet dabei eine Polymerisation der Kunststoffmoleküle statt, so dass eine molekulare Verbindung entsteht, die ein Auftrennen verunmöglicht. Es versteht sich von selbst, dass auf die inneren Grenzflächen auch graphische Muster aufgedruckt werden können, falls dies erwünscht ist. Im Zusammenhang mit anderen Ausführungsbeispielen wird darauf noch häher eingegangen. Die Oberflächen der so gebildeten Karte 1 sind plan und können in herkömmlicher Weise bedruckt oder beschichtet werden. Das charakteristische Kennzeichen ist dabei vollständig unzugänglich in der Karte eingeschlossen. Dabei ist dieses Kennzeichen im normalen Fall in der Aufsicht nicht erkennbar, da die Dickenunterschiede allein in Aufsicht nicht wahrgenommen werden können. Dies erschwert es, dieses Kennzeichen durch entsprechenden täuschenden Farbaufdruck zu imitieren, wie dies bei herkömmlichen Wasserzeichen auf Papier versucht wird, wo bekanntlich auch in der Aufsicht ein kleiner Farbkontrast erkennbar ist.A larger layer thickness therefore leads to a greater light absorption. The influence of the transparent half part 2 can be disregarded here, since its light absorption coefficient B is negligibly small in comparison with that of the opaque layer. The opaque half part 3 is now formed in such a way that regions 4 of increased thickness are formed to form a watermark-like effect. In contrast, zones 5 of smaller thickness are formed in adjacent areas 5, so that lighter areas 5 are created when looking around the dark-appearing areas, as is characteristic of the appearance of conventional watermarks. In Fig. 2b this is indicated schematically by arrows, which on the one hand represent the uniformly incident light and on the other hand the light passing through, the thickness of the arrows corresponding to the light intensity. The relief in the opaque half part 3 is embossed in such a way that the total amount of material remains constant and only a shift in the amount of material from the areas 5 to the areas 4 takes place. This means that the average thickness over the areas 4 and 5 provided with a relief structure is equal to the thickness of the rest of the map. The impression is taken with an egg ner embossing mold of known type. The transparent half part 2 is provided with a corresponding, opposing embossing, the embossing mold used for this purpose being preferably electrolytically molded from the first embossing mold. The two half parts are then inseparably formed into a single part by laminating. Polymerization of the plastic molecules takes place along the interface of the two half parts provided with the relief structure, so that a molecular connection is formed which makes separation impossible. It goes without saying that graphic patterns can also be printed on the inner interfaces, if this is desired. This will be discussed in more detail in connection with other exemplary embodiments. The surfaces of the card 1 thus formed are flat and can be printed or coated in a conventional manner. The characteristic mark is completely inaccessible in the card. In the normal case, this indicator is not recognizable in the supervision, since the differences in thickness cannot be perceived in supervision alone. This makes it difficult to imitate this characteristic by correspondingly deceptive color printing, as is attempted with conventional watermarks on paper, where, as is known, a small color contrast can also be seen in the top view.

In Fig. 3 ist ein vorteilhaftes Ausführungsbeispiel zum erläuterten Prinzip vergrössert und schematisch im Schnitt dargestellt. Dabei bedient man sich zum Aufbau der reliefartigen Struktur der Grenzfläche der Rastertechnik. In den Bereichen 4, welche in Durchsicht dunkler erscheinen sollen, wird dabei die Höhe h4 der einzelnen punktförmigen Rasterelemente 7 grösser gewählt, als die Höhe h6 der Rasterelemente im Hauptbereich der Karte. In benachbarten Bereichen 5 dagegen wird deren Höhe h5 kleiner gewählt. Massgebend für die Lichtdurchlässigkeit ist jeweils die über die einzelnen Bereiche gemittelte Dicke des opaken Halbteils 3, falls die einzelnen Rasterpunkte visuell nicht mehr oder nur noch schlecht aufgelöst werden. Diese gemittelten Dicken werden so gewählt, dass der bereits anhand der Fig. 1 und 2 erläuterte Effekt in der Durchsicht erkennbar ist. Wiederum findet hier bei der Prägung nur eine Materialumlagerung von den hellen Bereichen 5 in die dunklen Bereiche 4 statt. Die Ausgestaltung des Reliefs als Raster erlaubt diese Materialumlagerung in einfacher Weise und vergrössert zudem die Grenzfläche, entlang welcher die beiden Halbteile zusammengefügt werden, so dass ein noch besserer Zusammenhalt der aus den beiden Halbteilen zusammengefügten, einstückigen Karte entsteht. Der transparente Halbteil 2 ist wiederum gegengleich ausgebildet.In Fig. 3, an advantageous embodiment of the principle explained is enlarged and shown schematically in section. To do this, the raster technique is used to build up the relief-like structure of the interface. In areas 4, which should appear darker when viewed, the height h 4 of the individual punctiform grid elements 7 is chosen to be greater than the height h 6 of the grid elements in the main area of the map. In contrast, in adjacent areas 5 their height h 5 is chosen to be smaller. The thickness of the opaque half part 3, averaged over the individual areas, is decisive for the light transmission. if the individual halftone dots are no longer or only poorly resolved visually. These averaged thicknesses are chosen so that the effect already explained with reference to FIGS. 1 and 2 can be seen in the review. Again, during embossing, there is only a material shift from the light areas 5 to the dark areas 4. The design of the relief as a grid allows this material rearrangement in a simple manner and also increases the interface along which the two half parts are joined, so that the one-piece map composed of the two half parts is held together even better. The transparent half part 2 is in turn designed to be opposite.

Die reliefartige Grenzfläche, welche mit Hilfe des erläuterten Vorgehens innerhalb der Karte 1 entsteht, kann auch zur Kennzeichnung der Karte in Aufsicht ausgestaltet sein. Soll dies mit Durchsichtskennzeichnung in der Art des Wasserzeichens verbunden sein, so ist weiterhin der eine Halbteil aus transparentem, der andere aus opakem thermoplastischem Kunststoff anzufertigen.The relief-like interface, which is created within the card 1 with the aid of the explained procedure, can also be configured to identify the card in supervision. If this is to be associated with see-through marking in the manner of the watermark, then one half part must continue to be made from transparent, the other from opaque thermoplastic.

Ein Ausführungsbeispiel, welches dies illustriert, ist in den Fig. 4 und 5 gezeigt. In Fig. 4 ist eine linienartig aufgebaute Reliefstruktur am opaken Halbteil 3 gezeigt, wobei im mittleren Bereich eine der Fig. 3 entsprechende Ausgestaltung erkennbar ist. Diese Struktur ist mit einem Farbstreifen 8 bedruckt, der in senkrechter Aufsicht geradlinig verläuft. Der so ausgestaltete opake Halbteil 3 wird mit einem gegengleichen, transparenten Halbteil (nicht dargestellt) zu einer Karte vereinigt, von welcher in Fig. 5 schematisch ein Abschnitt dargestellt ist. In Fig. 5a ist die Durchsicht dargestellt. Erkennbar ist das gerade Linienmuster 8 sowie die das Wasserzeichen bildenden Bereiche 4 und 5. Wird die Karte in schräger Aufsicht betrachtet, wie dies in Fig. 5b gezeigt ist, so erscheint das Linienmuster 8 leicht gewellt, und das Wasserzeichen verschwindet. Bei genauer Betrachtung in der schrägen Aufsicht kann das Wasserzeichen an der grösseren Amplitude der Wellung im Linienmuster 8 noch erkannt werden. Die Verbildung von Durchsichts-und Aufsichtskennzeichnung erhöht die Schwierigkeit der Fälschung solcher Karten und vergrössert deshalb deren Sicherheit weiter.An embodiment which illustrates this is shown in FIGS. 4 and 5. FIG. 4 shows a relief structure of linear construction on the opaque half part 3, a configuration corresponding to FIG. 3 being recognizable in the central region. This structure is printed with a color strip 8, which runs in a straight line in vertical supervision. The opaque half part 3 designed in this way is combined with a transparent half part (not shown) of the same type to form a card, a section of which is shown schematically in FIG. 5. The review is shown in FIG. 5a. The straight line pattern 8 as well as the areas 4 and 5 forming the watermark can be seen. If the map is viewed from an oblique view, as shown in FIG. 5b, the line pattern 8 appears slightly wavy and the watermark disappears. Beige closer inspection in the oblique view, the watermark can still be recognized by the larger amplitude of the corrugation in the line pattern 8. The formation of inspection and supervisory labeling increases the difficulty of counterfeiting such cards and therefore further increases their security.

Schliesslich sei anhand der Figuren 6 und 7 eine weitere Ausgestaltung der Erfindung gezeigt, welche sowohl in der Aufsicht als in der Durchsicht eine Kennzeichnung erlauben. In den Fig. 6a und b sind zwei Varianten dieser Ausgestaltung im Schnitt gezeigt. Die Grenzfläche zwischen den beiden Halbteilen 2 und 3 weist jeweils eine linienrasterförmige Reliefstruktur auf. Diese wird auf einem der Halbteile mit einem Druckmuster versehen, dessen Erscheinung sich in der Aufsicht je nach dem Betrachtungswinkel ändert (Fig.6a), bzw. das insbesondere in der Durchsicht je nach Betrachtungswinkel einen ändernden Helligkeitseindruck ergibt. (Fig.6b) Die erstgenannte Variante beruht auf einer Reliefstruktur, welche mindestens angenähert eine Rechteckform 9 aufweist. Die Seitenflanken sowie Talsohlen sind dabei mit einer Farbschicht 10 versehen, während die Kuppen frei von Farbe bleiben. In der senkrechten Aufsicht sind die Farbflächen 10 im wesentlichen als Striche wahrnehmbar, während sie sich in schräger Aufsicht zu einer durchgehenden Farbfläche zusammenschliessen. Werden Farben mit kleiner Lichtdurchlässigkeit verwendet, so wird in der Durchsicht je nach Durchsichtswinkel eine unterschiedliche Helligkeit festgestellt. Bei senkrechter Durchsicht wird demzufolge beim Beispiel von Fig.6a eine grössere Helligkeit wahrgenommen als bei schräger Durchsicht. In der Variante gemäss Fig. 6b besitzt die Reliefstruktur im Querschnitt im wesentlichen eine Dreiecksform 11. Die eine Flanke 12 ist mit einer Farbschicht 12 versehen, während die andere Flanke frei von Farbe ist. Wiederum wird je nach Aufsichtswinkel ein verändertes Erscheinungsbild des Druckmusters sichtbar, und zwar ändernd zwischen blossem Strichmuster (Pfeil links in Fig. 6b) bis zu einer durchgehenden Farbfläche (Pfeil rechts in Fig. 6b). In der Durchsicht verhält sich die wahrnehmbare Helligkeit asymmetrisch, falls eine Farbe mit geringer Lichtdurchlässigkeit verwendet wird. Wird die Karte ausgehend von der senkrechten Durchsicht auf die eine Seite geneigt, so nimmt die Helligkeit zu, bei Neigung auf die andere Seite nimmt sie dagegen ab.Finally, a further embodiment of the invention is shown on the basis of FIGS. 6 and 7, which permit identification both in the top view and in the view. 6a and b show two variants of this embodiment in section. The interface between the two half parts 2 and 3 each has a linear grid-shaped relief structure. This is provided with a printed pattern on one of the half parts, the appearance of which changes in the top view depending on the viewing angle (FIG. (Fig. 6b) The first-mentioned variant is based on a relief structure which has at least approximately a rectangular shape 9. The side flanks and valley bottoms are provided with a color layer 10, while the tops remain free of color. In the vertical view, the color areas 10 are essentially perceptible as lines, while in oblique view they merge to form a continuous color area. If colors with low light transmission are used, a different brightness is determined in the view depending on the view angle. With a vertical view, a greater brightness is perceived in the example of FIG. 6a than with an oblique view. In the variant according to FIG. 6b, the relief structure essentially has a triangular shape 11 in cross section. One flank 12 is provided with a color layer 12, while the other flank is free of color. Again, depending on the angle of view, a changed appearance of the print pattern becomes visible, namely changing between mere line pattern (arrow left in Fig. 6b) to a solid color area (arrow right in Fig. 6b). In perception, the perceptible brightness behaves asymmetrically if a color with low light transmission is used. If the card is tilted on the one side from a vertical view, the brightness increases, but when it is tilted on the other side it decreases.

Die erläuterten 'Ausführungsarten können selbstverständlich ohne weiteres derart ausgestaltet werden, dass zusätzlich in Durchsicht noch ein Wasserzeichen erscheint, wie oben anhand der Fig. 1 bis 4 erläutert. Ferner können darin weitere Sicherheitsmerkmale vorgesehen werden, wie etwa in Fig. 7a und b gezeigt. Diese Ausführung der Anordnung gemäss Fig. 6a weist ein entsprechendes Druckmuster auf, das jedoch mit Lücken 13 versehen ist, welche in bestimmten Richtungen in Linie angeordnet sind. In Aufsicht (Fig. 7b) fällt dies nicht auf, wenn diese Struktur genügend fein ausgestaltet ist. Wird jedoch ein flacher Betrachtungswinkel gewählt, (Fig. 7a) so erscheinen deutlich helle Gassen in dunkler Umgebung. Dieser an sich von Banknoten her bekannte Effekt, wo allerdings eine unebene Oberfläche vorausgesetzt wird, lässt sich auf die erläuterte Weise ohne weiteres als zusätzliches Sicherheitsmerkmal bei ebenen Vollkunststoffarten anwenden.The described 'embodiments can be designed, of course, readily so as to additionally contain a watermark appears in phantom, as explained above with reference to FIGS. 1 to 4. Furthermore, further security features can be provided therein, such as shown in FIGS. 7a and b. This embodiment of the arrangement according to FIG. 6a has a corresponding printing pattern, which, however, is provided with gaps 13 which are arranged in a line in certain directions. In supervision (Fig. 7b), this is not noticeable if this structure is of sufficiently fine design. If, however, a flat viewing angle is selected (Fig. 7a), clearly bright alleys appear in a dark environment. This effect, which is known per se from banknotes, but where an uneven surface is assumed, can easily be used in the manner explained as an additional security feature for flat all-plastic types.

Es versteht sich von selbst, dass die ebenen Oberflächen derart gebildeter Kunststoffarten in der bekannten Weise bedruckt sein können. Für die Aufsichtskennzeichnung nach der beschriebenen Art sind an den entsprechenden Stellen Fenster im Aufdruck vorzusehen. Ferner können Teile der Karteninformation auch im Druckmuster an der Grenzfläche vorhanden sein.It goes without saying that the flat surfaces of plastic types formed in this way can be printed in the known manner. For the supervision marking according to the described type, windows have to be provided in the print at the appropriate places. Furthermore, parts of the map information can also be present in the print pattern at the interface.

Die beschriebene Anordnung mit einer reliefartig ausgebildeten, gegebenenfalls mit einem Druckmuster versehenen Grenzfläche zwischen zwei Kartenteilen, welche untrennbar verbunden werden, ergibt, wie oben dargestellt, mannigfache vorteilhafte Möglichkeiten der visuellen Sicherung derartiger Karten, welche bisher nicht gegeben waren. Dabei bleiben absolut plane Oberflächen erhalten. Prägungen in der Karte führen nicht zu einer Wölbung, wie dies bei den bisher bekannten Verbundenkarten der Fall war. Die Sicherheitsmerkmale sind Manipulationen unzugänglich.The arrangement described with a relief-like interface, possibly provided with a printed pattern, between two card parts, which are inseparably connected, results in manifold, as shown above partial possibilities of visually securing such cards, which were not previously available. Absolutely flat surfaces are preserved. Embossments in the card do not lead to a curvature, as was the case with the previously known compound cards. The security features are inaccessible to manipulation.

Eine besonders vorteilhafte Anwendung der Durchsichtskennzeichnung mittels der reliefartigen Ausbildung der Grenzfläche des opaken Teils 3 und des transparenten Teils 2 gemäss den Fig. 1 bis 3 besteht darin, dass die Reliefstruktur jeweils nach dem Portrait des Kartenbesitzers ausgebildet wird. In wasserzeichenartiger Form erscheint damit dieses Portrait in der Durchsicht und kann jederzeit mit einer Fotographie des Besitzers oder diesem selbst verglichen werden. Damit kann ein zusätzliches, individuelles Erkennungsmerkmal geschaffen werden. Dies ist insbesondere deshalb möglich, weil die reliefartige Struktur der Grenzfläche stufenlos ineinander übergehende Bereiche unterschiedlicher Dicke aufweisen kann, welche - im Gegensatz zum herkömmlichen Wasserzeichen, welche meist zweistuig ausgestaltet sind - in der Durchsicht ein Bild mit stufenloser Helligkeitsvariation zwischen einem Maximum und einem Minimum ergeben.A particularly advantageous application of the see-through marking by means of the relief-like design of the interface of the opaque part 3 and the transparent part 2 according to FIGS. 1 to 3 is that the relief structure is formed in each case according to the portrait of the card owner. This portrait appears in watermark-like form when viewed and can be compared at any time with a photograph of the owner or himself. This enables an additional, individual identifier to be created. This is possible in particular because the relief-like structure of the interface can have continuously merging areas of different thicknesses, which - in contrast to conventional watermarks, which are usually designed in two stages - result in a transparent image with stepless brightness variation between a maximum and a minimum .
