Abstract
A silver halide color photographic material is described, comprising 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 on a support, wherein at least one coupler represented by general formula (I) is contained in at least the green-sensitive emulsion layer: ##STR1## Moieties in the couplers are defined in the specification. The wavelength of the red-sensitive emulsion layer shows a defined maximum spectral sensitivity in the short wavelength side and wavelengths corresponding to 80%, 50%, 40%, 20% and 10% of the maximum sensitivity in defined wavelength regions. Similar values are given for the long wavelength side of spectral sensitivity.
