ANTECEDENTES DE IA INVENCIÓNBACKGROUND OF THE INVENTION
Hasta ahora en el mercado de la identificación existen los siguientes tipos de laminados holográficos: -Laminados holográficos metálicos con vaporización en vacío de depósito metálico, generalmente aluminio y laminados holográficos poliméricos constituidos por varias capas superpuestas termoadheridas y que se deslaminan reversiblemente aplicando calor. Los laminados metálicos de aluminio (Al) que también puede ser de plataSo far in the identification market there are the following types of holographic laminates: -Holographic metal laminates with Vacuum vaporization of metallic deposit, generally aluminum and polymeric holographic laminates consisting of several super-bonded thermo-bonded layers that are reversibly delaminated by applying heat. Metal laminates of aluminum (Al) which can also be silver
(Ag) o de bismuto (Bi), son opacos y por tanto no pueden proteger eficazmente un documento de identidad por transparencia una vez termolaminadas las capas constitutivas de dicho documento. Por tanto se aplican como un elemento de seguridad con carácter meramente disuasorio. Tienen estos dos tipos de laminados holográficos el inconveniente de que pueden ser recortados del documento original y reutilizados en documentos fraudulentamente reproducidos de los respectivos documentos originales, con cambio de datos personales y fundamentalmente con sustitución de la imagen facial impresa original por otra identidad que generalmente con ambos tipos reseñados de laminados holográficos solo se consigue proteger de una manera testimonial. Dichos laminados metálicos opacos son aplicados en documentos de identidad y tarjetas de permisos de conducción tanto de PVC como de policarbonato.(Ag) or bismuth (Bi), are opaque and therefore cannot effectively protect an identity document by transparency once the constituent layers of said document have been heat-laminated. Therefore they are applied as a security element with a purely deterrent character. These two types of holographic laminates have the disadvantage that they can be cut from the original document and reused in fraudulently reproduced documents of the respective original documents, with change of personal data and fundamentally with replacement of the original printed facial image with another identity that generally with Both types of holographic laminates are only protected in a testimonial way. These opaque metallic laminates are applied in identity documents and driving license cards of both PVC and polycarbonate.
-Laminados holográficos transparentes tipo HRI (high reflexión index) basados en depósito de SZn o de TiOa que son transparentes y por tanto podrían proteger tanto a la imagen facial impresa o grabada con rayo láser como a los datos personales de un documento de identidad termolaminado. Hasta ahora no ha sido posible aplicar de manera práctica y efectiva este tipo de laminado HRI transparente por diversas razones inherentes a la propia estructura tecnológica del laminado HRI para protección eficaz de documentos de identidad contra reproducción y manipulación fraudulentas y falsificación de los mismos. Existen por tanto ya experiencias acumuladas no satisfactorias en documentos de identidad con laminado holográfico HRI. De un lado, no es posible aplicar este tipo de laminado holográfico en documentos integrales de policarbonato (PC) debido a la gran dureza del PC con el grave inconveniente de que para termolaminar y termosoldar las distintas capas del documento es necesario aplicar temperaturas superiores a 195°C de fusión superficial del PC, con lo que no es posible utilizar hologramas HRI transparentes de protección de documentos de PC ya que a esa temperatura la capa holográfica HRI pierde en gran manera sus cualidades reflectivas. Asi mismo no es posible integrar un holograma HRI transparente cubriendo y protegiendo la totalidad de la superficie de un documento integralmente de policarbonato porque representa una barrera en la termolaminación de sus capas y se deslamina muy fácilmente. Se utilizan por tanto hologramas transparentes muy restringidos en forma zonal de reducido tamaño que son más un testimonio que una protección ya que a través de dicho holograma HRI se realiza el grabado con rayo láser de la imagen facial y por tanto permite la manipulación fraudulenta posterior del documento mediante retoque con rayo láser para cambiar los rasgos de la imagen original grabada con rayo láser por otra identidad. Por otro lado, hasta ahora los laminados holográficos HRI presentan deficiencias estructurales que hacen que la capa del soporte (carrier) de poliéster se deslamine y separe por la acción prolongada del agua (a las 24 horas se produce la deslaminación o separación) lo cual es un inconveniente grave para documentos de identidad de alta seguridad. Asi mismo, el laminado holográfico HRI termolaminado en un documento o tarjeta de identidad, se deslamina y separa sin daño aparente alguno con la acción de 'disolventes y reactivos químicos tan comunes como la acetona, amoniaco hidrocarburos etc, lo cual representa un grave inconveniente para la seguridad del documento de identidad ya que dicho laminado holográfico HRI puede por tanto ser reutilizado fraudulentamente en otro documento reproducido del original con imagen facial sustituida por otra identidad. Es necesario añadir que también los laminados holográficos metalizados opacos adolecen igualmente aunque en menor medida de los inconvenientes de deslaminación mencionados. Resumiendo estos argumentos se constata que todos los laminados holográficos del mercado tienen el muy grave inconveniente de que la capa holográfica que cubre toda la superficie es de un espesor no superior a las lOμ y constituye el punto débil para la deslaminación fraudulenta de los documentos termolaminados.-HRI (high reflection index) transparent holographic laminates based on SZn or TiOa deposits that are transparent and could therefore protect both the facial image printed or laser-etched and the personal data of a thermo-laminated identity document. Until now it has not been possible to apply this type of transparent HRI laminate in a practical and effective way for various reasons inherent in the technological structure of the HRI laminate for effective protection of identity documents against fraudulent reproduction and manipulation and falsification of them. There are therefore already accumulated unsatisfactory experiences in identity documents with HRI holographic laminate. On the one hand, it is not possible to apply this type of holographic laminate in Comprehensive polycarbonate (PC) documents due to the high hardness of the PC with the serious drawback that in order to heat-laminate and heat-weld the different layers of the document it is necessary to apply temperatures above 195 ° C of PC's surface melting, which is not possible use transparent HRI holograms for PC document protection since at that temperature the HRI holographic layer greatly loses its reflective qualities. Likewise, it is not possible to integrate a transparent HRI hologram covering and protecting the entire surface of an integrally polycarbonate document because it represents a barrier in the thermolamination of its layers and is easily delaminated. Therefore, very restricted transparent holograms are used in a small-sized zonal form that are more a testimony than a protection since through said HRI hologram laser engraving of the facial image is performed and therefore allows subsequent fraudulent manipulation of the document by means of retouching with laser beam to change the features of the original image recorded with laser beam for another identity. On the other hand, so far the HRI holographic laminates have structural deficiencies that cause the layer of the polyester carrier (carrier) to be delaminated and separated by the prolonged action of the water (after 24 hours the delamination or separation occurs) which is a serious inconvenience for high security identity documents. Likewise, the HRI thermo-laminated holographic laminate in a document or identity card is delaminated and separated without any apparent damage with the action of 'solvents and chemical reagents as common as acetone, ammonia hydrocarbons etc., which represents a serious inconvenience for the security of the identity document since said HRI holographic laminate can therefore be fraudulently reused in another document reproduced from the original with a facial image replaced by another identity. It is necessary to add that the opaque metallic holographic laminates also suffer, although to a lesser extent, the aforementioned delamination problems. Summarizing these arguments, it is found that all holographic laminates on the market have the very serious disadvantage that the holographic layer covering the entire surface is not thicker than 10μ and constitutes the weak point for fraudulent delamination of thermo-laminated documents.
La presente invención se refiere a cuatro estructuras especificas estratificadas de capas para documentos de identidad de la más elevada seguridad y alta adherencia en los que se han superado todas las graves deficiencias anteriormente expuestas de forma que los documentos y tarjetas de identidad termolaminados con dichas estructuras de capas con los materiales específicos objeto de la presente invención no se deslaminan por la acción continuada del agua, y siempre se dañan irreversiblemente en los intentos de deslaminación por la acción de los disolventes y reactivos químicos comunes.The present invention relates to four stratified specific structures of layers for identity documents of the highest security and high adhesion in which all the serious deficiencies set forth above have been overcome so that the documents and identity cards thermo-laminated with said structures of Layers with the specific materials object of the present invention are not delaminated by the continued action of water, and are always irreversibly damaged in delamination attempts by the action of common chemical solvents and reagents.

Likewise, the polyurethane-based adhesive can be selectively substituted by a two-component polyurethane-based thermoadhesive deposit with the addition of acrylic acid derivative.
En la realización preferida se incluyen además, las combinaciones posibles de la estructura central básica con los conjuntos de protección exterior, ya que se pueden configurar estructuras en las que al menos uno de los conjuntos de protección exterior no es aplicado y también es posible que no esté dotado de la capa de su respectivo depósito holográfico.In the preferred embodiment, possible combinations of the basic core structure with the external protection assemblies, since structures can be configured in which at least one of the exterior protection assemblies is not applied and it is also possible that it is not provided with the layer of its respective holographic deposit.
