PURPOSE:To obtain an image having specified high quality irrespectively of a processing temp. and time by incorporating a specific compd. in a photosensitive material for color diffusion transfer contg. DRR (DYE<theta>Releasing<theta>Redox) compd. CONSTITUTION:A compd. expressed by the formula I is incorporated in a photosensitive material contg. one photosensitive silver halide autopositive emulsion layer and one kind of DRR compd. combined therewith on a base. The above- mentioned compd. expressed by the formula ( I ) is added adequately in an amt. of about 0.1-60mol% with respect to the DRR compd. in the case of adding the same to the same layer as the DRR compd. and 1-200mol% with respect to the DRR compd. in the case of adding the same to a different layer. The embodiment of the compd. expressed by the formula I is exemplified by the compd. expressed by the formulas II, III. In the formulas, R<1> dnotes H, an alkyl group, halogen group, sulfo group, R<2>, R<3> denote H, alkyl group and R<4> denotes an aryl group.
