Abstract
A silver halide photographic light-sensitive material having a high color reproducibility is disclosed. The photographic comprises a support having thereon a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer in which the red sensitive emulsion layer contains a non-color-forming compound represented by the following formula [I], a compound represented by the following formula [II] and at least one cyan-forming coupler represented by the following formula [III] or [IV]: ##STR1## The photographic material is improved in spectral aborption, stability and maximum density of the cyan image thereof.
