ABSTRACT:
An image-receiving element adapted to the provision of a diffusion transfer photograph and having a preprinted security pattern between contiguous layers thereof is disclosed. The pattern comprises a patterning agent and a binder therefor preferentially adhesive to the contiguous layer closest in proximity to the image-receiving layer of such element. Diffusion transfer photographs prepared from the image-receiving element carrying the preprinted security pattern are useful in the production of an information-bearing document such as an ID card.
