Description

ABSTRACT:
A silver halide color photographic light-sensitive material is disclosed, comprising (1) a coupler having a dye moiety, the maximum absorption wavelength of which is shifted to the shorter wavelength by a bond cleaving, directly or through a timing group, due to a coupling reaction with an oxidized product of an aromatic primary amine-based developing agent, and, as a result of the reaction, forming a compound having a dye portion which has the original maximum absorption wavelength before shifting; and (2) a compound releasing a development inhibitor directly or through a timing group upon reacting with the oxidized aromatic primary amine-based developing agent.
