Abstract
A silver halide color photographic lightsensitive material includes at least one emulsion layer on a support. At least one of the emulsion layers contains a coupler represented by formula (1) below and a coupler represented by formula (2) below at a molar ratio of 1:9 to 9:1. In formulas (1) and (2), each of R1, R2, R3, and R4 independently represents a hydrogen atom or a substituent. Each of X1 and X2 represents a hydrogen atom or a group capable splitting off by coupling with the oxidized form of a developing agent. At least one of X1 and X2 is a hydrogen atom.
