    • A color photographic light-sensitive material comprising a support having thereon, in sequence:(1) a blue-sensitive silver halide emulsion layer containing, dispersed in the emulsion using a high-boiling organic solvent, a yellow coupler represented by the following general formula (I): ##STR1## with the weight ratio of the high-boiling organic solvent for dispensing the coupler to the yellow coupler being 1.0:1 or less;(2) a green-sensitive silver halide emulsion layer containing a magenta coupler represented by the following general formula (II): ##STR2## (3) a red-sensitive silver halide emulsion layer containing a cyan coupler represented by the following general formula (III): ##STR3## (4) an ultraviolet light absorbing layer containing an ultraviolet light absorbent represented by the following general formula (IV): ##STR4## in which the substituents X, Z, and R.sub.1 -R.sub.12 are as defined in the specification. The color photographic light-sensitive material provides a dye image which is resistant to fading or discoloration by light, and in particular provides color prints having a well-balanced fading of the dye image composed of the three yellow, magenta and cyan colors.
    • 一种彩色照相感光材料,其中包含其上的载体,其顺序为:(1)感蓝卤化银乳剂层,其含有使用高沸点有机溶剂分散在乳液中的黄色成色剂,由下列通式 (I):用于分配成色剂的高沸点有机溶剂与黄色成色剂的重量比为1.0:1或更小的(I) (2)含有由以下通式(II)表示的品红色成色剂的感绿卤化银乳剂层:(2)(3)含有下列物质的青色成色剂的感红卤化银乳剂层 (III):(III)(4)包含由以下通式(IV)表示的紫外线吸收剂的紫外光吸收层:其中取代基X,Z和 R1-R12如说明书中所定义。 彩色摄影感光材料提供了耐受光的褪色或变色的染料图像,特别是提供了由三种黄色,品红色和青色组成的染料图像的平衡褪色的彩色印刷品。
