摘要: There is disclosed a light-sensitive silver halide photographic material containing a compound represented by the formula (I): ##STR1## wherein G, R.sub.1, R.sub.2 and X have the same meanings as defined in the specification.The 1-naphthol coupler which is contained in the light-sensitive silver halide photographic material is high in reactivity with an oxidized product of a color forming developing agent and can efficiently impart imagewise photographic effects to light-sensitive silver halide photographic materials.
