Silver halide color photographic sensitive material
专利汇可以提供Silver halide color photographic sensitive material专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the browning of an colored image due to the influences of heat, humidity and light by dispersing a specified cyan coupler in the title material using a water-insoluble and an org. solvent soluble homopolymer or copolymer and by incorporating a specified UV absorber in the nonphotosensitive layer of the sensitive material. CONSTITUTION:The silver halide color photographic sensitive material comprises a red sensitive, a green sensitive and a blue sensitive silver halide photosensitive emulsion layers provided on a supporting body, and compds. shown by formula I and/or II are incorporated in the emulsion layer, and a compd. shown by formula III is incorporated in at least one layer of the nonphotosensitive layers positioned on the side opposite to the emulsion layer provided on the supporting body. In formulas I-III, R1, R2 and R4 are each an aliphatic, an aromatic or a heterocyclic ring group which may be substd., R3, R5 and R6 are each hydrogen or halogen tom, an aliphatic, an aromatic or acylamino group, Y1 and Y2 are each hydrogen atom. or a group capable of being released by coupling reaction with the oxidant of a developing main agent, (n) is 0 or 1, R7-R11 are the same or the different with each other, and are each hydrogen atom., etc. Thus, the durability of a cyan colored image against the heat, a wet heat and the light can be improved at the same time, and the shelf-life of the formed colored image is improved.，下面是Silver halide color photographic sensitive material专利的具体信息内容。
