Abstract
Abstract An excellent bacteriocidal effect with no influence on the photographic performances, is achieved by incorporating into at least one hydrophilic colloid layer of a light-sensitive silver halide photographic material, at least one compound of the general formula [1]: wherein R' represents a hydrogen atom, a straight-chain or a branched-chain alkyl group, a cyclic alkyl group, an alkenyl group, an aralkyl group, an aryl group, a heterocyclic group, an alkylamido group, an arylamido group, an alkylthioamido group, an arylthioamido group, an alkylsulfoamido group or an arylsulfoamido group; R 2 and R 3 each represent a hydrogen atom, a halogen atom, an alkyl group, a cyclic alkyl group, an aryl group, a heterocyclic group, a cyano group, an alkylthio group, an arylthio group, an alkylsulfoxide group or an alkylsulfonyl group; however, said alkyl group, cyclic alkyl group, alkenyl group, aralkyl group, aryl group and heterocyclic group may have substituents.
