摘要： A silver halide color photographic light-sensitive material of which the color reproducibility and printing suitability are kept improved against the variation of photographing conditions, such as a change in light source, is disclosed. The photographic material comprises a support and provided thereon a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein at least one of said emulsion layers is of three-layer structure comprising a low-speed elemental emulsion layer, a medium-speed elemental emulsion layer and a high speed emulsion layer arranged in this sequence from the side facing the support, and a maximum color density of said medium-speed emulsion layer is not more than 0.35.

摘要： A silver halide color photographic light-sensitive material is disclosed. The light-sensitive material comprises a support, having thereon a red sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein the red-sensitive comprises a low-speed red-sensitive silver halide emulsion sublayer, a medium-seed red-sensitive silver halide emulsion sublayer and a high-speed red-sensitive silver halide emulsion layer provided in this order from the support, and sensitivities S.sub.600, S.sub.620, S.sub.640, S.sub.660 and S.sub.680 of the medium speed red-sensitive emulsion sublayer which are each determined as reciprocal of the exposure amount of light of wavelength of 600 nm, 620 nm, 640 nm, 660 nm and 680 nm necessary for forming an image having a density of fog+0.1 in the medium speed red-sensitive emulsion sublayer, respectively, satisfy the following relation; 0.5S.sub.640
