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 compound capable of releasing a group represented by the general formula (I) described below upon the reaction with the oxidation product of a developing agent: ##STR1## wherein W represents an oxygen atom, a sulfur atom or a group ##STR2## (wherein R represents a hydrogen atom or an organic residue); X represents an electron withdrawing substituent; Y represents a hydrogen atom or a substituent; PUG represents a photographically useful group or a precursor thereof; X and Y each represents a divalent group and may be connected to each other to form a cyclic structure; and when W represents the group ##STR3## and R represents an organic residue, R and X or R and Y each represents a divalent group and may be connected to each other to form a cyclic structure.
