A dye-receiving element for producing a high-security, monolithic identification card, said element comprising a support having thereon a dye image-receiving layer adapted to receive a thermally-transferred dye image, said dye image-receiving layer containing indicia printed thereon approximately 40-120 .mu.m in width.
A process of producing a high-security, monolithic identification card comprising:
- (a) printing indicia approximately 40-120 .mu.m in width onto a dye-receiving element comprising a support having thereon a dye image-receiving layer;
- (b) imagewise-heating a dye-donor element comprising a support having thereon a dye layer;
- and
- (c) transferring a dye image to said dye-receiving element to form said high-security, monolithic identification card.
A high-security, monolithic identification card comprising a support having thereon printed indicia approximately 40-120 .mu.m in width and a dye image-receiving layer containing a thermally-transferred dye image.
A thermal dye transfer assemblage comprising:
- (a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a binder, and
- (b) a dye-receiving element comprising a support having thereon a dye image-receiving layer,
- said dye-receiving element being in a superposed relationship with said dye-donor element so that said dye layer is in contact with said dye image-receiving layer, said dye image-receiving layer containing indicia printed thereon approximately 40-120 .mu.m in width.
