Abstract
A silver halide color photographic material comprising a reflective support and coated thereon at least one each of a cyan dye-forming silver halide emulsion layer, a magenta dye-forming silver halide emulsion layer and a yellow dye-forming silver halide emulsion layer, each of the emulsion layers containing substantially silver iodide-free silver chloride or silver chlorobromide and respectively having spectral sensitivity peaks in different wavelength regions, at least one of the emulsion layers containing silver halide grains having an average grain size of 0.35 .mu.m to 0.65 .mu.m and a silver halide content of 0.19 g Ag/m.sup.2 or less, the total silver amount in all the silver halide emulsion layers being 0.78 g/m.sup.2 or less, and a water-soluble or bleachable dye being available on the support in such an amount that the sensitivity of the silver halide emulsion layer having a sensitivity peak at the longest wavelength is reduced to 35 to 10% of the sensitivity in the absence of the water-soluble or bleachable dye, the sensitivity of the silver halide emulsion layer having a sensitivity peak at the second longest wavelength is reduced to 50 to 20% of the sensitivity in the absence of the water-soluble or bleachable dye, and the sensitivity of the silver halide emulsion layer having a sensitivity peak at the shortest wavelength is reduced to 70 to 30% of the sensitivity in the absence of said water-soluble or bleachable dye.
