ABSTRACT:
In accordance with this invention a photographic color diffusion transfer element is provided wherein said element comprises a single dimensionally stable transparent support and coated thereon in reactive association and in sequence (1) a mordant layer for binding diffusible dyes, (2) a light reflecting layer, (3) imaging layers comprising a radiation sensitive layer comprising silver halide and a diffusible dye forming layer comprising a diffusible dye forming compound, and (4) a barrier layer comprising a polymer that allows the passage of solutions for processing said element when said element is contacted with an external processing bath, and wherein said barrier layer impedes the diffusion out of said element of the diffusible dye formed from said diffusible dye forming compound. In another preferred embodiment, the sequential arrangement of layers next to the support is in the order: (1) imaging layers comprising a radiation sensitive layer comprising silver halide and a diffusible dye forming layer comprising a diffusible dye forming compound, ( 2) a light reflecting layer, (3) a mordant layer for binding diffusible dyes, (4) a barrier layer comprising a polymer that allows the passage of solutions for processing said element when said element is contacted with an external processing bath, and wherein said barrier layer impedes the diffusion out of said element of the diffusible dye formed from said diffusible dye forming compound.
