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.sup.1 represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole, benzoxazole, naphthothiazole or naphthoxazole nucleus;
• Z.sup.2 represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole nucleus;
• R.sup.1 and R.sup.2 each independently represents an alkyl group having 1-4 carbon atoms, a substituted alkyl group or anryl group;
• X.sup..crclbar. is an anion;
• n is 1 or 2 and when an intramolecular salt is formed, n is 1;
