ABSTRACT:
A photographic light-sensitive material containing a novel gelatin hardener is disclosed, which comprises as a gelatin hardener at least one compound represented by formula (I) ##STR1## wherein R.sup.1 and R.sup.2 each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group, or R.sup.1 and R.sup.2 together represent a nitrogen-containing heterocyclic ring; R.sup.3 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an aralkyl group, or an alkoxy group; and R.sup.4 represents a chemical bond, or an alkylene group, an arylene group, or a divalent group composed of these groups. The compound represented by formula (I) provides rapid hardening progress, prevents after-hardening, and does not undergo hardening inhibition when applied to silver halide color photographic materials.
