There is disclosed a coupler for photography represented by the formula: ##STR1## wherein R.sub.1 represents a branched alkyl group having 3 to 5 carbon atoms; R.sub.2 represents an aryl group; X represents a divalent linking group; Ar represents an aryl group; and Z is a hydrogen atom or a group eliminable through the coupling reaction with the oxidized product of an aromatic primary amine type color developing agent,and a light-sensitive silver halide photographic material comprising the same.The coupler mentioned above is not only excellent in solubility in organic solvents, but also can be easily purified, thus being capable of exhibiting excellent characteristics with respect to spectral absorption characteristics, sensitivity, color density, color staining as well as with respect to image storability such as light resistance, heat resistance and humidity resistance.
