A silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide photographic emulsion layer, wherein at least one layer selected from the emulsion layer and other hydrophilic colloid layers contains at least one alkynyl substituted heterocyclic quaternary ammonium salt represented by the following general formula (I):
wherein Z represents a non-metallic atomic group necessary to form a substituted or unsubstituted 5- membered or 6-membered heterocyclic ring to which a aromatic ring or a heterocyclic ring may further be condensed; RI represents a substituted or unsubstituted aliphatic group; X represents = C -or - N -; Q represents a non-metallic atomic group necessary to form a substituted or unsubstituted 4-membered to 12- membered non-aromatic hydrocarbon ring or substituted or unsubstituted non-aromatic heterocyclic ring; at least one of R1, a substituent for Z and a substituent for Q includes an alkynyl group; Y represents a counter ion necessary for charge balance; and n represents a number necessary to balance the charge.
