摘要： 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.

摘要： A silver halide color light-sensitive material is described, which is increased in sensitivity, is adapted to form an image of high contrast, or is accelerated in development by incorporating a small amount of a specific compound which imagewise releases a foggant or a development accelerator. This compound is represented by the formula: Coup-(TIME).sub.n -FA (wherein Coup represents a coupler radical capable of undergoing a coupling reaction with an oxidized product of an aromatic primary amine developing agent; TIME represents a timing group which is eliminated from Coup by the coupling reaction and, thereafter, releases FA; n is 0 or 1; and FA represents a group which is eliminated from Coup in the coupling reaction when n is 0, whereas FA is released from TIME when n is 1. The FA has adsorption properties with respect to silver halide grains and also has a substantial fogging action with respect to the silver halide grains).
