ABSTRACT:
In a diffusion transfer color photographic material including a photosensitive element comprising silver halide emulsion layers having associated therewith dye image forming materials, an image receiving element, and a liquid processing composition for developing the silver halide emulsion layers after image-wise exposure and diffusing the dye images formed into the image receiving element, the dye images formed are stabilized and the formation of stains at blank areas is effectively prevented by incorporating one or more N-.alpha.-sulfoalkylated amino acids into at least one of the photosensitive element, the image receiving element or the liquid processing composition. A process using the same is also disclosed.
