ABSTRACT:
A silver halide photographic light-sensitive material comprising a support bearing thereon a silver halide emulsion layer containing a diffusionproof coupler and being hardened with a hardening agent represented by Formula [II] and/or Formula [III] indicated below is enabled to acquire improved film properties and enjoy increased freedom from repression of latent image by using, as the diffusionproof coupler, a compound represented by Formula [I] indicated below: Formula [I] ##STR1## wherein R.sub.1 denotes a straight or branched alkyl group having 2 to 4 carbon atoms; R.sub.2 a ballast group; and X a hydrogen atom or a group capable of splitting off through reaction with the oxidation product of an aromatic primary amine type color developing agent. ##STR2## wherein R.sub.3 denotes a chlorine atom, a hydroxy group, an alkyl group, an alkoxy group, an amino group, an acylamino group, or a --OM group in which M denotes a monovalent metal atom; R.sub.4 has the same meaning as R.sub.3 except for the omission of the chlorine atom; R.sub.5 and R.sub.6 independently denote a chlorine atom, a hydroxy group, an alkyl group, an alkoxy group, or a --OM group in which M denotes a monovalent metal atom; Q and Q' independently denote a linking group --O--, --S--, or --NH--; L denotes an alkylene group or an arylene group; and p and q independently denote 0 or 1.
