Abstract
Abstract A silver halide photographic light-sensitive material having, upon a substrate, a blue-sensitive silver halide emulsion layer, a green-sensitive emulsion layer and a red-sensitive emulsion layer. The silver halide grains contained in the blue-sensitive emulsion layer is optically sensitized for maximum spectral sensitivity in the wavelength region of 450 to 500 nm, and at least one emulsion layer other than the blue-sensitive layer contains a magenta coupler represented by the following formula, the substituents of which are defined within the Specification. ##STR1## Photographic materials thus formed have both an increased blue and green sensitivity.
