ABSTRACT:
In accordance with this invention a photographic color diffusion transfer element and process for its development are provided. The element comprises a single dimensionally stable support, wherein said support comprises an opaque and light reflecting layer, and coated thereon in reactive association and in sequence (1) a mordant layer for binding diffusible dyes, (2) a stripping layer, (3) one or more layers comprising radiation sensitive silver halide and a diffusible-dye forming coupler, and (4) a barrier layer comprising a polymer that (a) allows the passage of solutions for processing said element when said element is contacted with an external processing bath and (b) impedes the diffusion out of said element of the diffusible dye formed from said diffusible-dye forming coupler, and wherein said diffusible-dye forming coupler is of the structure
