Photographic image transfer element and process

Abstract

a photographic element is disclosed which includes a support having as a coating thereon a radiation-sensitive layer capable of selectively releasing protons in exposed areas. In direct contact with the radiation-sensitive layer is an image-forming dye capable of shifting between a mobile and an immobile form in an aqueous medium upon protonation of a carboxy or amine substituent. The portion of the dye remaining mobile after imagewise protonation can be transferred to a receiver sheet to form a viewable dye image.
