    • A silver halide color photographic light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide emulsion layer contains at least one cyan dye forming coupler and at least one polymer latex represented by the following formula (I):--(A).sub.x --(B).sub.y -- (I)wherein A represents a repeating unit derived from at least one ethylenically unsaturated monomer having at least one --COOM group (wherein M represents a hydrogen atom or a cation) in its molecule; B represents a repeating unit derived from at least one ethylenically unsaturated monomer which does not have the --COOM group; and x and y represent weight percentages of A and B, respectively, x represents a number of from 25 to 85, y represents a number of from 75 to 15, and x+y=100.The silver halide color photographic light-sensitive material is excellent in rapid processing suitability and provides a color photograph having an excellent image quality in which degradation of color balance does not occur with the lapse of time after processing since the blix discoloration of cyan image in that the cyan dye formed by color development turns into its leuco-body in a bleaching or blixing solution is substantially prevented.
    • 一种卤化银彩色照相感光材料,其包括其上提供有至少一个卤化银乳剂层的载体,其中所述卤化银乳剂层含有至少一种青色染料形成成色剂和至少一种由下式(I ): - (A)x-(B)y-(I)其中A表示衍生自至少一种具有至少一个-COOM基团的烯属不饱和单体(其中M表示氢原子或阳离子)的重复单元 分子; B表示来自不具有-COOM基团的至少一种烯属不饱和单体的重复单元; 并且x和y分别表示A和B的重量百分数,x表示25至85的数,y表示75至15的数,x + y = 100。 卤化银彩色摄影感光材料具有优异的快速加工适应性,并且提供了一种具有优异图像质量的彩色照片,其中自从蓝绿色图像的混色变色以来,经过加工后的时间不会发生颜色平衡的劣化,因为 基本上防止了通过显色形成的青色染料在漂白或混合溶液中变成其隐色体。
