Abstract (en)
[origin: US4464454A] A method for producing an information carrier in the form of a card, such as an identification card or pass, as well as an information carrier produced in accordance with this method. The information carrier comprises a plurality of plastic layers combined with one another into a block, at least one of which contains a photograph of the bearer and/or his fingerprint and/or other readable or machine-readable data in the form of a photographic layer. This photographic layer is produced and incorporated into the sandwich of plastic layers making up the identification card in that a specially prepared film is exposed to light, developed, fixed and dries, and then the carrier layer of this film sandwich is removed from the emulsion after the emulsion has entered into an adhesive bond with a first plastic carrier layer, this adhesion being substantially greater than the adhesion of the emulsion to the film's auxiliary carrier, which is to be removed.
