ABSTRACT:
In a color diffusion transfer photographic material which comprises a photosensitive element containing at least one silver halide emulsion layer having associated therein a non-diffusible dye image-providing material, an image-receiving element for immobilizing therein diffusible dye formed by the oxidation reaction of the dye image-providing material and a primary aromatic amino color developing agent to form dye images, and a processing composition for developing the exposed silver halide in the silver halide emulsion layer and transferring the diffusible dye formed into the image-receiving layer with at least one of the photosensitive elements, the image-receiving element or the processing composition containing a primary aromatic amino color developing agent or a precursor thereof, with the photosensitive element and/or the image-receiving element of the photographic material containing at least one of divinyl sulfone and a divinyl sulfone derivative represented by the formula (I): ##STR1## wherein B represents an atomic group necessary for forming an ammonium group, a sulfonium group or a phosphonium group; X.sup.- represents an acid anion; and n is 0, 1 or 2.
