摘要: A silver halide color photographic light-sensitive material is disclosed having excellent spectral characteristics. This is achieved by using at least one phenol cyan coupler of Formula [I] dispersed with a phthalic ester of Formula [II].
wherein R represents a straight or branched alkyl or cycloalkyl radical, R 2 represents a hydrogen atom, a halogen atom or a monovalent organic radical, R 3 represents a straight or branched alkyl radical, R 4 and R 5 each independently represent a branched alkyl radical, Z represents a hydrogen atom or a radical capable of being eliminated on coupling with an oxidation product of a color developing agent, n represents 0 or an inteqer from 1 to 3;
wherein R 6 and R 7 each independently represent an alkyl, alkenyl, aryl or cycloalkyl radical.摘要翻译: 公开了具有优异的光谱特性的卤化银彩色照相感光材料。 这通过使用分散有式[II]的邻苯二甲酸酯的至少一种式[I]的苯酚青成色剂来实现。 其中R表示直链或支链烷基或环烷基,R 2表示氢原子,卤素原子或单价有机基团,R 3表示直链或支链烷基,R 4和R 5各自独立地表示支链烷基,Z表示 氢原子或能够在与彩色显影剂的氧化产物偶联时被消除的基团,n表示0或1至3的整数; 其中R6和R7各自独立地表示烷基,烯基,芳基或环烷基。
