Identification document
First Claim
1. An identification document comprising:
- a core layer bearing at least one indicium thereon;
two layers of a substantially transparent polymer fixed to the core layer on opposed sides thereof; and
at least one image-receiving layer capable of being imaged by dye diffusion thermal transfer, the image-receiving layer being fixed to one of the layers of substantially transparent polymer on the side thereof remote from the core layer.

Abstract
An over-the-counter type identification document is prepared by forming at least one first indicium (typically invariant data common to a large number of identification documents) on a core layer, sandwiching this core layer between a pair of substantially transparent polymer layers, providing an image-receiving layer on one or both outer surfaces of the resulting sandwich, forming a second indicium (typically variable data relating only to a single identification document) on the image-receiving layer(s) and laminating a protective layer or layers over the image-receiving layer(s). The identification document displays improved durability and security and can be rendered substantially identical in appearance to documents produced by known central issue production methods.

7. A process for preparing an identification document, which process comprises:
-
forming at least one first indicium upon a core layer; affixing to the indicium-carrying core layer two layers of substantially transparent polymer, one of said layers being affixed to each surface of the core layer; providing, on one of the layers of substantially transparent polymer, on the side thereof remote from the core layer, an image-receiving layer capable of being imaged by dye diffusion thermal transfer; printing by dye diffusion thermal transfer at least one second indicium on the image-receiving layer, said second indicium being different from the first indicium on the core layer; and affixing a protective layer over the image-receiving layer bearing the second indicium. - View Dependent Claims (8, 9, 10, 11, 12)
