Abstract
Abstract A silver halide color photographic material comprising a support and formed thereon at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer, wherein gradients γ P R , γ P G and γ P B in monochromatic exposure of each wavelength giving peak sensitivities are 0.80 < γ P R 0.80 < γ P G 0.65 < γ P B and gradients γR, γG and γB in standard white light source exposure are γ R < 0.65 γ G < 0.65 γ B < 0.75, and a method for producing a color image using the same. The photographic material has a high saturation and excellent color and contrast reproducibility.
