Abstract
Abstract A color photographic light-sensitive material comprising a cupport having coated thereon at least one silver halide emulsion layer. 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 1 and R 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 1 and R 2 together represents an oxo group; and R 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.
