    • 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 color photographic light-sensitive material contains at least one dye forming coupler represented by the following formula (I):
      wherein R 1 represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group or a substituted or unsubstituted amino group; X=Y represents C=O, C=NR 2 , P=O or S=O; R 2 represents an aliphatic group or an aromatic group; Z represents a group capable of being released upon a reaction with the oxidation product of a developing agent; m and n each represents an integer of 1 or 2; R 1 and R 2 , R 1 and Z or R 2 and Z may be combined with each other to form a ring; and when m is 2, two R 1 's may be the same or different, or may be combined with each other to form a ring.
      The dye forming coupler represented by the formula (I) provides a yellow dye having excellent hue, a large molecular extinction coefficient and storage stability, and the silver halide color photographic light-sensitive material containing the yellow dye forming coupler is excellent in color reproducibility, sharpness and color image fastness.
    • 1,一种卤化银彩色摄影感光材料,其特征在于它包括一个载体,在载体上至少有一层卤化银乳剂层,其中卤化银彩色照相感光材料含有至少一种由下式(I)表示的成色剂: R1表示取代或未取代的脂族基团,取代或未取代的芳族基团,取代或未取代的杂环基,取代或未取代的烷氧基,取代或未取代的芳氧基,取代或未取代的烷硫基,取代或未取代的芳硫基 或取代或未取代的氨基; X = Y表示C = O,C = NR 2,P = O或S = O; R2代表脂族基团或芳族基团; Z表示能够在与显影剂的氧化产物反应时释放的基团; m和n各自表示1或2的整数; R1和R2,R1和Z或R2和Z可以相互结合形成环; 当m为2时,两个R1可以相同或不同,或者可以相互结合形成环。 由式(I)表示的形成染料的成色剂提供具有优异色调,大分子消光系数和储存稳定性的黄色染料,并且含有形成黄色染料的成色剂的卤化银彩色照相感光材料具有优异的颜色再现性, 锐度和彩色图像的牢度。
