PURPOSE:To improve the discoloration of pigment images formed from each couplers due to a light by providing the nonphotosensitive layer of an emulsion contg. a specified U.V. absorber at a far position and/or a near position separated from a supporting body, seeing from a photosensitive silver halide emulsion layer which exists at the most far position from the supporting body, on the supporting body. CONSTITUTION:The titled material provides the nonphotosensitive layer contg. the dispersion at the prescribed side of the supporting body, and said dispersion is obtd. by emulsifying the solution contg. a mixture of at least one kind of the U.V. absorber selected from the compds. shown by formulas I and II, and at least one kind of a homopolymer or a copolymer which is insoluble in water and soluble in an org. solvent, and has a repeating unit shown by formula III in a main or a side chain of the polymer. In the formulas I and II, R1-R3 are each hydrogen or halogen atom., etc., R4 and R5 are each hydrogen atom. or alkyl group, etc., X is -CO- or -COO- group, (l), (m) and (n) are each a positive integer of 1-4. Thus, the excellent photographic sensitive material having the improved photodurability of a pigment image is obtd. |
