摘要： A silver halide color photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having thereon a silver halide emulsion layer containing silver halide grains each containing an iridium compound and a compound containing iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium or platinum; elemental sulfur; and two kinds of specified monomethine cyanine sensitizing dyes. The light sensitive material is improved in the reciprocity law failure property and the sensitivity fluctuation due to variation of atmosphere humidity.
