PROBLEM TO BE SOLVED: To provide a color diffusion transfer photosensitive material by which a high sensitivity clear image in a diffusion transfer system can be obtained and which is excellent in uniformity of an image and by which an image rarely having chromatic turbidity and a stain can be obtained. SOLUTION: In a color diffusion transfer photosensitive material having a photosensitive element, an image receiving element and a developing processing element, it is composed of an alkaline processing composition which contains at least one kind of coloring reducing agent expressed by a formula and at least one kind of diffusive pigment forming coupler in either of photosensitive layers of a photosensitive element having a silver halide emulsion containing photosensitive layer of at least a single layer and on which the developing processing element neither contains a developing agent nor an auxiliary developing agent. In the formula, Cαrepresents a carbon atom. Z represents a carbamoyl group, an acyl group, an alkoxy carbonyl group and an aryl oxycarbonyl group, and Q represents an atomic group to form an unsaturated ring by bonding to Cα.
