Silver halide photographic material

A silver halide photographic material comprising on a support at least one silver halide emulsion and comprising at least one methine dye represented by formula (II):

• ##STR85## wherein Z.sub.3 and Z.sub.4 each represents atoms necessary to complete a benzothiazole or naphthothiazole ring, provided that when both of Z.sub.3 and Z.sub.4 are benzothiazole rings, both of said benzothiazole rings contain an electron donating substituent group at the 5- and/or 6-position of the benzothiazole ring;
• R.sub.4 and R.sub.5 each represents an alkyl group, an aryl group or a heterocyclic group;
• R.sub.6 and R.sub.7 each represents an alkyl group;
• L.sub.7 and L.sub.8 each represents a methine group;
• M.sub.1 represents an ion for neutralizing electric charges;
• and m.sub.1 is a number of the ion, including 0, necessary for neutralizing electric charges in a dye molecule.
