A silver halide color photographic light-sensitive material comprises a novel cyan dye-forming coupler or a combination of a specific cyan dye-forming coupler with an .alpha.-pivaloylacetoanilide type yellow dye-forming coupler or a pyrazoloazole type magenta dye-forming coupler, the specific cyan dye-forming coupler being contained in the silver halide emulsion layer in the form of an emulsion of lipophilic fine particles obtained by mixing the coupler with at least one water-insoluble and organic solvent-soluble homo- or co-polymer to form a dispersion. The silver halide color photographic light-sensitive material is excellent in the reproduction of yellow, magenta and cyan colors and has low fog of cyan. Thus, the light-sensitive material can provide color images excellent in the fastness of the cyan color images. The cyan dye-forming coupler is represented by general formula (II): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group or a heterocyclic group; R.sub.2 represents a group or atom which can be bonded with the heterocyclic ring; X represents a hydrogen atom or a group which can be eliminated; Y represents a divalent bonding group having at least one amido bond and/or ester bond; Z represents a dissociative group; A, B, C, D and E each represents a nitrogen atom or a carbon atom a which hydrogen atom is bonded, provided that one or two of them represent a nitrogen atom; and n represents 0, 1 or 2.
一种银卤化物彩色感光材料,包括一种新型的青色染料形成偶合剂或特定青色染料形成偶合剂与α-对伯酰乙酰苯胺型黄色染料形成偶合剂或吡唑咯唑型洋红色染料形成偶合剂的组合,其中特定青色染料形成偶合剂以与至少一种水不溶性和有机溶剂可溶性的同聚物或共聚物混合形成分散体的脂溶性细粒子乳液的形式存在于银卤化物乳剂层中。该银卤化物彩色感光材料在黄、洋红和青色的再现方面表现出色,并且青色的雾度很低。因此,该感光材料可以提供色彩牢度优异的彩色图像。青色染料形成偶合剂由一般式(II)表示:其中R1表示脂肪族基、芳香族基或杂环基;R2表示可与杂环环结合的基团或原子;X表示氢原子或可消除的基团;Y表示至少有一个酰胺键和/或酯键的二价键合基团;Z表示可解离的基团;A、B、C、D和E分别表示氮原子或碳原子,其中氢原子被键合,但其中一个或两个表示氮原子;n表示0、1或2。
