Abstract
Abstract A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support base having thereon a silver halide emulsion layer and a high molecular compound having a repeating unit containing a residue of benzotriazoles. The repeating unit may be represented by the general formula (I) ##STR1## wherein R 1 represents a hydrogen atom or a lower alkyl group, L represents a divalent bonding group, and X represents a monovalent group of benzotriazoles. Improved antifogging agent effects are obtained by utilizing the high molecular compound of applicants' invention in connection with silver halide photographic light-sensitive materials.
