Abstract
Abstract A color photographic light-sensitive material is described containing a cyan dye forming coupler represented by formula (I) ##STR1## wherein R 1 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; R 2 and R 3 each represents hydrogen, a halogen atom, an alkyl group, an aryl group, an alkoxy group, an alkoxycarbonyl group, an alkylcarbonyl group, an arylcarbonyl group, an alkylcarbamoyl group, an arylcarbamoyl group wherein said groups may be substituted or unsubstituted, or a nitryl group; and X represents hydrogen or a coupling-off group; also a double bond may be formed between the carbon atom at the 3-position and the carbon atoms at the 4-position. The color photographic light-sensitive material provides color images having excellent fastness to light and heat.
