ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, the color photographic light-sensitive material containing a cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein R represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a heterocyclic group; X represents a hydrogen atom or a group capable of being released upon an oxidative coupling reaction with a developing agent; R.sup.1 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group.
The cyan dye forming coupler represented by the general formula (I) has a good solubility in an organic solvent having a high boiling point and a high dye forming rate even in a color developing solution which does not contain benzyl alcohol and provides a cyan color image having a high maximum density and excellent fastness to light. Further, 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.
