Definitions
- the invention relates to an identity card formed as a laminate of at least three plastic films and carrying an image in a printing technique, said image comprising a line pattern as is usual for securities, said pattern being distributed over at least two film faces within the laminate and wherein the plastic material of the films is polyvinylchloride.
- the invention relates to a method for laminating an identity card of transparent polyvinylchloride film while enclosing an ink printed image within the laminate comprising the steps of stacking the films to be laminated while enclosing the said image and laminating same by application of pressure onto their full surface areas and of heat.
- a similar identity card and a similar method for forming an identity card are disclosed in FR-A-2 279 548.
- the enclosed printed image being distributed among at least two faces of the films forming the laminate is inaccessible for tampering with said print other than by taking the laminate apart.
- the adherence between the films is good, separation of the laminate will cause serious and unrepairable damage of the films and of the printed image in particular. Repair of the card after separating the laminate without any visible damage is virtually impossible.
- Good adherence of the films as required having this object in mind is prejudiced by the printed image that locally bars direct contact between the films.
- FR-A-1 032 615 discloses a method for enveloping any document comprising the steps of arranging said document between two transparent polyvinyl films, and of compressing the said arrangement while successively applying heat to and cooling the array.
- the enclosing films are larger than the document such that said films envelop the document in a secure border where the covering films are in direct contact.
- DE-A-2 225 471 discloses an identity card formed as a laminate of three polyvinylchloride films, viz. a core ply and two transparent cover films.
- this disclosure (example 10) the laminating process - at a temperature of 150°C and a pressure of 20 kg/cm 2 (2 MPa) - will cause embedding of an imprint on the core ply into the adjacent films, thus requiring actual fusion of the films. Any imprint on any of the films before laminating the same will slightly run out and will lose their definition.
- This disclosure in a general sense mentions a pressure range of lamination from 1 to 50 kg/cm 2 . However, the examples given do not support this allegation.
- US-A-3 457 661 discloses a laminated identity card comprising a plurality of plasticfilms and photoprint, using a vinyl-base ink of the heat- resistant type which makes a permanent bond with the print carrier film for printing indicia on both sides of an opaque film to be enclosed when laminating at a temperature in the range from 225 to 250°F (107 to 121°C) and a pressure in the range from 200 to 300 psi (1.4 to 2.1 MPa).
- good adherence of the films in the above identity card is attained in that said image is printed using an adhesive thermosetting vinyl ink, a so-called HSV ink, for bonding of the adjacent or superposed film with the aid of the ink, and in that the ratio of printed to unprinted surface area amounting to at most 50% of an interface between two films, the image being printed "bled-off".

- the films were compiled to form a package and four of such packages were placed between two chromium nickel polishing plates in a laminating press and heated therein up to 150°C, while applying a force of 10 kN. During cooling the force was raised to 0.6 MN. After heating the process took less than 9 minutes.

Description
- The invention relates to an identity card formed as a laminate of at least three plastic films and carrying an image in a printing technique, said image comprising a line pattern as is usual for securities, said pattern being distributed over at least two film faces within the laminate and wherein the plastic material of the films is polyvinylchloride.
- Furthermore the invention relates to a method for laminating an identity card of transparent polyvinylchloride film while enclosing an ink printed image within the laminate comprising the steps of stacking the films to be laminated while enclosing the said image and laminating same by application of pressure onto their full surface areas and of heat.
- A similar identity card and a similar method for forming an identity card are disclosed in FR-A-2 279 548. The enclosed printed image being distributed among at least two faces of the films forming the laminate is inaccessible for tampering with said print other than by taking the laminate apart. Provided that the adherence between the films is good, separation of the laminate will cause serious and unrepairable damage of the films and of the printed image in particular. Repair of the card after separating the laminate without any visible damage is virtually impossible. Thus the card is protected against falsification in the above sense. Good adherence of the films as required having this object in mind is prejudiced by the printed image that locally bars direct contact between the films.
- FR-A-1 032 615 discloses a method for enveloping any document comprising the steps of arranging said document between two transparent polyvinyl films, and of compressing the said arrangement while successively applying heat to and cooling the array. However, the enclosing films are larger than the document such that said films envelop the document in a secure border where the covering films are in direct contact.
- DE-A-2 225 471 discloses an identity card formed as a laminate of three polyvinylchloride films, viz. a core ply and two transparent cover films. According to this disclosure (example 10) the laminating process - at a temperature of 150°C and a pressure of 20 kg/cm2 (2 MPa) - will cause embedding of an imprint on the core ply into the adjacent films, thus requiring actual fusion of the films. Any imprint on any of the films before laminating the same will slightly run out and will lose their definition. This disclosure in a general sense mentions a pressure range of lamination from 1 to 50 kg/cm2. However, the examples given do not support this allegation.
- US-A-3 457 661 discloses a laminated identity card comprising a plurality of plasticfilms and photoprint, using a vinyl-base ink of the heat- resistant type which makes a permanent bond with the print carrier film for printing indicia on both sides of an opaque film to be enclosed when laminating at a temperature in the range from 225 to 250°F (107 to 121°C) and a pressure in the range from 200 to 300 psi (1.4 to 2.1 MPa).
- According to the invention good adherence of the films in the above identity card is attained in that said image is printed using an adhesive thermosetting vinyl ink, a so-called HSV ink, for bonding of the adjacent or superposed film with the aid of the ink, and in that the ratio of printed to unprinted surface area amounting to at most 50% of an interface between two films, the image being printed "bled-off".
- The method for forming the same identity card is characterized in that the step of imprinting the image comprises use of an adhesive thermosetting vinyl ink, a so-called HSV-ink, for bonding of the adjacent or superposed film with the aid of the ink.
- To illustrate the invention the following description of an embodiment is given.
- A card was manufactured by laminating four polyvinylchloride films with a format of 350 x 480 mm as follows.
- Two of the films with a thickness of 0.2 mm were unilaterally offset printed image-wise with an HSV-ink.
- As cover films a transparent film having a thickness of 0.1 mm and a transparent film having a thickness of 0.3 mm were used. The films were compiled to form a package and four of such packages were placed between two chromium nickel polishing plates in a laminating press and heated therein up to 150°C, while applying a force of 10 kN. During cooling the force was raised to 0.6 MN. After heating the process took less than 9 minutes.

2. A method for laminating an identity card of transparent polyvinylchloride films while enclosing an ink printed image within the laminate comprising the steps of stacking the films to be laminated while enclosing the said image and laminating same by application of pressure onto their full surface areas and of heat, characterized in that said laminating step comprises the steps of compressing the stack, subsequently heating same while maintaining said pressure and finally cooling the film while maintaining said pressure and in that said step of imprinting the image comprises use of an adhesive thermosetting vinyl ink, a so-called HSV ink, for bonding of the adjacent or superposed film with the aid of the ink.
