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 and Z each represents an oxygen atom, a sulfur atom or a group of ##STR2## X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 each represents a hydrogen atom or an organic residue; PUG represents a photographically useful group; n represents 1 or 2; any two of X.sub.1, X.sub.2, X.sub.3, X.sub.4, X.sub.5 and PUG each represents a divalent group and may be connected to each other to form a cyclic structure; and when n represents 2, two Z's, two X.sub.3 's and two X.sub.4 's may be the same or different. The compound used in the present invention is chemically stable and capable of releasing a photographically useful group at the desired rate, diffusibility of the photographically useful group released is large and the function area of the photographically useful group released can be effectively controlled. The silver halide color photographic light-sensitive material containing the compound has good stability during preservaton thereof and either provides a color image having good image qualities such as sharpness, graininess and color reproducibility, etc. or exhibits high sensitivity.
