    • 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.
    • 卤化银彩色照相感光材料包括新型的青色染料形成成色剂或特定的形成青色染料的成色剂与α-对甲酰基乙酰苯胺型黄色染料形成成色剂或吡唑并唑型品红色染料形成成色剂的组合, 通过将成色剂与至少一种水不溶性和有机溶剂可溶性均聚物或共聚物混合而形成的亲脂性细颗粒乳液形式的卤化银乳剂层中所含有特定的青色成色剂, 分散。 卤化银彩色摄影感光材料在黄色,品红色和青色的再现方面是优异的,并且具有低的青色雾。 因此,感光材料可以提供在青色图像的牢度方面优异的彩色图像。 青色染料成色剂由通式(II)表示:其中R 1表示脂族基团,芳族基团或杂环基团; R2表示可以与杂环结合的基团或原子; X表示氢原子或可被除去的基团; Y表示具有至少一个酰胺键和/或酯键的二价键合基​​团; Z表示离解基团; A,B,C,D和E各自表示氮原子或氢原子键合的碳原子a,条件是它们中的一个或两个表示氮原子; n表示0,1或2。

The color photographic light-sensitive material contains a cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein Z represents ##STR2## R represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; X represents a hydrogen atom or a group capable of being released upon an oxidative coupling reaction with a developing agent; Y represents ##STR3## --O-- or --S--; R.sup.1 and R.sup.2, which may be the same or different, each represents a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted alkylcarbonyl group, a substituted or unsubstituted arylcarbonyl group, a substituted or unsubstituted carbonyl group, a substituted or unsubstituted acylamino group or a nitryl group or R.sup.1 and R.sup.2 together represents an oxo group; and R.sup.3 represents a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group.The color photographic light-sensitive material provides a cyan color image having preferred spectral absorption characteristics for color reproduction and excellent fastness to light and heat. Furthermore, a decrease in optical density of the cyan color image is not substantially observed even when the color photographic light-sensitive material is processed with a bleaching solution which has a weak oxidation power or a bleaching solution which is exhausted.
