Abstract (en)
[origin: US4298217A] The application discloses an identity card consisting of a plurality of layers, of which the cover layers are highly transparent films and the layers of the card core are films of moderate to low transparency, as a result of added pigment. One core layer carries information, which can be read directly, if desired, above a security print, while the other core layer has an additional security marking, such as a guilloche print, a marking which can be read optically only with the aid of a special lamp, or a piece of magnetic tape. All the layers consist of polymers which can be fused together to form a laminate which is fused together like a monolithic block and which does not have any interfaces which allow a mechanical, thermal or chemical separation.
