ABSTRACT:
A silver halide light-sensitive color photographic material which comprises a coupler represented by formula [I]; ##STR1## wherein A represents a coupler residue that is capable of releasing the remaining group of said coupler upon reaction with an oxidation product of a developing agent; L represents a timing group which is capable of releasing the rest of the group after said remaining group being released from A; n represents 0 or 1; X represents an oxygen or sulfur atom; Y represents a --NHSO.sub.2 R.sub.1 ' group, a ##STR2## group or a --NHCOR.sub.1 ' group, in which formulas R.sub.1 ' and R.sub.2 ' independently represent a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group; R.sub.1 and R.sub.2 independently represent a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group; R.sub.3 represents a substituent group; m represents 0, 1 or 2, provided that when m is 2, two R.sub.3 s may be different, and that two of R.sub.1, R.sub.2 and R.sub.3 or two of R.sub.1 ', R.sub.2 ' and R.sub.3 ' may be divalent groups to form a ring structure.
