ABSTRACT:
There is disclosed a silver halide photographic light-sensitive which is capable of providing a rapid processing as well as a high sensitivity and in which a change in an aging time in exposing through processing provides less performance fluctuation and therefore an excellent stability. The silver halide photographic light-sensitive material comprises a support and provided thereon at least one light-sensitive silver halide emulsion layer and at least one non-light-sensitive layer, wherein at least one of the above light-sensitive emulsion layers contains a silver halide emulsion grain which comprises silver bromochloride having a silver chloride content of 90% or more or silver chloride each containing substantially no silver iodide and in which 50% or more of a grain surface consists of a (111) plane; and further, at least one of the non-light-sensitive layers contains a compound represented by the following Formula (I): ##STR1## wherein X represents a hydrogen atom, a hydroxyl group, an amino group, or a sulfonamido group; R.sup.11 and R.sup.12 each represent the same group as that defined for X, an alkyl group, an aryl group, an amido group, a ureido group, an alkylthio group, an arylthio group, an alkoxy group, or an aryloxy group, and R.sup.11 and R.sup.12 may cooperate to form a carbon ring or a heterocyle; when X is a hydrogen atom, R.sup.11 represents a hydroxyl group, an amino group, or a sulfonamido group; R.sup.13 represents a hydrogen atom, a halogen atom, a sulfo group, a carboxyl group, an alkyl group, an acyl group, an oxycarbonyl group, a carbamoyl group, a sulfonyl group, or a sulfamoyl group; and, the compound represented by Formula (I) has a molecular weight of 390 or more.
