Abstract
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).
