ABSTRACT:
A two-equivalent cyan dye forming coupler represented by the general formula (I) substituted with at least one substituent represented by general formula (II), having substituents as defined in the specification. This coupler has excellent color forming properties and good dispersibility as well as good color hue and excellent fastness to heat and light. The color photographic material containing the two-equivalent cyan dye forming couplers does not exhibit a decrease in color density of cyan color images even when it is processed with a bleaching solution which has a weak oxidation power or a bleaching solution which is exhausted.
