ABSTRACT:
A silver halide color photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer formed on a support wherein the light-sensitive material contains a compound represented by the following general formula (I): ##STR1## wherein A is a coupler residual or an oxidation-reduction group, X.sub.1 is an oxygen atom or a sulfur atom, X.sub.2 is an oxygen atom, a sulfur atom or NX.sub.6 group, W is a carbon atom or a sulfur atom, X.sub.3, X.sub.4, X.sub.5 and X.sub.6 are each a hydrogen atom or an organic residual, any two of X.sub.3, X.sub.4 and X.sub.5 can be bivalent groups which form a ring, PUG is a photographically useful group capable of bonding at a hetero-atom and, in the formula (I), n.sub.1 is 1 if W is a carbon atom, and either 1 or 2 if W is a sulfur atom. If n.sub.1 is 2, two X.sub.1 can either be identical or different. On the other hand, n.sub.2 is either 1 or 2. If n.sub.2 is 2, two X.sub.3, two X.sub.4, and two x.sub.5 are either identical or different.
