PURPOSE:To improve the color reproducibility of the titled material, and to stabilize an image against heat, temperature and light, and to prevent the generation of a Y-stain due to the light by incorporating a phosphate type compd. and a UV absorber in a compd. shown by a prescribed formula at the same time. CONSTITUTION:The titled material comprises at least one layer of a silver halide emulsion layer mounted on a supporting body. And, at least one layer of said emulsion layers contains at least one kind of the compd. shown by the formula, and at least one kind of the phosphate compd., and the UV absorber are incorporated in the same layer and an another layer, respectively. In the formula, R1-R4 are each a substituting group, and two groups among groups R1-R3 do not contain hydrogen atom, R4 contains one of a substituting group -NHSO2, X is hydrogen atom or a substituting group capable of being released by a coupling reaction with the oxidant of an aromatic primary amine developing main agent. |
