摘要:
A novel silver halide photographic material is described, comprising a compound represented by formula (I): ##STR1## wherein Q represents a nonmetallic atomic group required to be connected to carbon atom and nitrogen atom to form a monocyclic or condensed heterocyclic ring therewith; L represents a divalent group; n represents an integer of 0 to 2; M.sup.1 represents a hydrogen atom, ammonium ion or metallic ion; and R.sup.1 and R.sup.2 each represents a hydrogen atom, alkyl group, ammonium ion or metallic ion and may be the same or different or may be connected to each other to form a 5- or 6-membered ring. In a preferred embodiment, at least one of R.sup.2 and R.sup.1 represents a hydrogen atom, ammonium ion or metallic ion.
