Silver halide photographic material

Abstract

A silver halide photographic material comprising on a support at least one silver halide emulsion layer having a silver halide content of not lower than 90 mol %, wherein a silver halide emulsion in at least one of said silver halide emulsion layers having a silver chloride content of not lower than 90 mol % contains at least one compound represented by formula (I): ##STR1## wherein Z.sub.1 and Z.sub.2 each represents an atomic group required for forming a nitrogen-containing five-membered or six-membered heterocyclic ring; Q.sub.1 and Q.sub.2 each represents a methylene group; R.sub.1 and R.sub.2 each represents an alkyl group; R.sub.3 represents an alkyl group, an aryl group or a heterocyclic group; L.sub.1, L.sub.2, L.sub.3, L.sub.4 and L.sub.5 each represents a methine group; n.sub.1 and n.sub.2 each represents 0 or 1; M.sub.1 represents a counter ion for neutralizing electric charge; and m.sub.1 represents a number not less than 0 required for neutralizing electric charge in the molecule.
