Abstract
Abstract Color photographic light sensitive materials are disclosed, comprising a cyan dye forming coupler represented by formula (I) ##STR1## wherein A represents a cyan coupler residue, but the --NHCO group does not bond to A in the active position of A, R 1 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, R 2 represents hydrogen or a substituted or unsubstituted alkyl group, and the various positions of the phenyl group of the formula (I) may be substituted with from 1 to 3 substituents selected from the group consisting of hydrogen, a halogen atom, an alkyl group or an alkoxy group.
