Abstract
Disclosed is a silver halide color photographic material comprising at least one yellow coupler-containing silver halide emulsion layer (BL) spectrally sensitized such that the specific spectral sensitivity range falls within the scope of from 400 nm to 520 nm, at least one magenta coupler-containing silver halide emulsion layer (GL) spectrally sensitized such that the specific spectral sensitivity range falls within the scope of from 470 nm to 620 nm, and at least one cyan coupler-containing silver halide emulsion layer (RL) spectrally sensitized such that the specific spectral sensitivity range falls within the scope of from 540 nm to 700 nm, wherein the center of gravity of the sensitivity wavelength of the GL's spectral sensitivity distribution (.lambda..sub.G) falls within the range of from about 520 nm to about 580 nm, the center of gravity of the sensitivity wavelength of the RL's spectral sensitivity distribution (.lambda..sub.R) falls within the range of from about 590 nm to about 650 nm, and the center of gravity of the sensitivity wavelength of the BL's spectral sensitivity distribution (.lambda.B) falls within the range of from about 430 nm to about 480 nm, and that the material satisfies at least one of the following conditions (a), (b), (c), and (d):
