Silver halide photographic material

Claim 1

A silver halide photographic material that contains at least one compound represented by the general formula (2 ) shown below and at least one compound selected from the group consisting of the compounds represented by the general formulas (3) and (4) shown below: ##STR46## where Z 1 represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole, benzoxazole, naphthothiazole or naphthoxazole nucleus; Z 2 represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole nucleus; R 1 and R 2 each independently represents an alkyl group having 1-4 carbon atoms, a substituted alkyl group or anryl group; X.sup.⊖ is an anion; n is 1 or 2 and when an intramolecular salt is formed, n is 1; ##STR47## where R 3 represents a hydrogen atom, a straight-chained or branched 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 alkylsulfamido group or an arylsulfamido group; R 4 and R 5 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a cyclic alkyl group, an aryl group, a cyano group, an alkylthio group, an arylthio group, an alkylsulfoxide group, an alkylsulfonyl group, or a heterocyclic group; ##STR48## where R 6 1 s a hydrogen atom, a lower alkyl group or a hydroxymethyl group; and R 7 is a hydrogen atom or a lower alkyl group.
