摘要:
A silver halide color photographic light-sensitive material has at least one light-sensitive silver halide emulsion layer on a support, contains a pyrazoloazole-based coupler, and further contains a compound represented by Formula (I) and/or Formula (II) below:Formula (I) A--(L.sub.1).sub.j --(L.sub.2).sub.m --[(L.sub.3).sub.n --PUG].sub.sFormula (II) A--L.sub.4 --L.sub.5 --PUGwhere A represents a coupler moiety or an oxidation-reduction group, each of L.sub.1 and L.sub.3 represents a divalent timing group, L.sub.2 represents a timing group with a valency of 3 or more and does not use electron transfer via a conjugated system, L.sub.4 represents a coupling group such as --OCO--, L.sub.5 represents a group for releasing PUG by electron transfer along a conjugated system or L.sub.4, PUG represents a photographically useful group, each of j and n independently represents 0, 1, or 2, m represents 1 or 2, and s represents a number obtained by subtracting 1 from a valence number of L.sub.2 and an integer of 2 or more. This silver halide color photographic light-sensitive material is excellent in sharpness, color reproducibility, and desilvering properties.
