摘要： A silver halide color photographic sensitive material is disclosed. The material is comprised of a substrate having a silver halide emulsion layer position thereon and a cyan dye forming coupler. The coupler is reresented by the general formula (I): ##STR1## wherein R represents a substituted or nonsubstituted alkyl group, aryl group or heterocyclic group, X represents a group capable of releasing by an oxidative coupling reaction with a developing agent, and R.sup.1 represents a substituted or nonsubstituted alkyl group or aryl group. The coupler of the invention can be easily dissolved in a high boiling point organic solvent and makes possible production of a light sensitive material having a high dye forming rate, high maximum color density and good fastness to light. Furthermore, the couplers prevent a large decrease in density when the bleaching solution utilized has a weak oxidation ability.
