Abstract
Disclosed is a silver halide color photographic light-sensitive material having at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one red-sensitive silver halide emulsion layer on the support, wherein the maximum sensitivity wavelength .lambda..sub.B of the spectral sensitivity distribution in said blue-sensitive silver halide emulsion layer at 400 nm.ltoreq..lambda..sub.B .ltoreq.470 nm, the sensitivity of said blue-sensitive silver halide emulsion layer at 480 nm does not exceed 40% of the sensitivity at the maximum sensitivity wavelength .lambda..sub.B and the gradient of said blue-sensitive silver halide emulsion layer after blue light separation exposure .gamma..sub.SB and the gradient of said blue-sensitive silver halide emulsion layer after white light exposure .gamma..sub.WB bears the relationship of .gamma..sub.SB /.gamma..sub.WB .ltoreq.1.25. The silver halide color photographic light-sensitive material according to this invention is capable of exactly reproducing the hues that have been difficult to reproduce, particularly the hues of red to magenta colors and the hues of green colors such as blue-green and green without being accomplished by degradation of the reproducibility for the primary colors.
