Abstract
Abstract Card formed as a laminate of at least three copolymer or homopolymer polyvinylchloride films and carrying an image in a printing technique by applying a heat setting vinyl ink, said image being enclosed in the laminate. The films forming the card, have a good adherence which can be enhanced in that the printed image in an interface between two films covers at most 50% of the surface area, and the image being printed "bled-off".

A card formed as a laminate of at least three plastic films and carrying an image in a printing technique and being distributed over two film faces within the laminate, characterized in that the plastic material of the films is a copolymer or homopolymer polyvinylchleride, and in that the image is printed with a thermosetting vinyl ink, a so-called HSV ink.
Claim 2
Dependent Claim

A card according to claim 1, characterized in that the printed image is substantially a line pattern as usual for securities, the ratio of printed to unprinted surface area amounting to at most 50% in an interface between two films, the image being printed "bled-off".
Claim 4
Independent Claim
80 words
A method for laminating a card of plastic films while enclosing an ink-printed image within the laminate, characterized by stacking the films to be laminated while enclosing the image and compressing same by application of pressure onto their full surface areas, subsequently heating the films while maintaining said pressure and finally cooling the films while maintaining said pressure, the transparent plastic films consisting of copolymer or homopolymer polyvinylchloride, and the printing ink being a thermosetting vinyl ink, a so-called HSV-ink.
