Abstract
There is disclosed a silver halide color photographic light-sensitive material that contains, in photographic constitutional layers on a support, a hydrazine-series reducing agent for color formation, and a phenol-series magenta coupler having an acylamino group at the 5-position, and/or a naphthol-series cyan coupler having an amido group at the 5-position. The light-sensitive material makes low-replenishment and low-discharge processing possible, and exhibits good color reproducibility and good color-forming property.
