wherein Z represents an atomic group necessary for forming a monocyclic or condensed heterocyclic ring composed of a carbon atom or carbon atoms and a nitrogen atom or nitrogen atoms; L, represents a divalent organic group; m represents 0 or 1; L2 represents -CONR-, -NRCO-, -SO2NR-, NRS02, -OCO-, -COO-, -S-, -NR-, -CO-, -SO-, -S02-, -OCOO-, -NRCONR'-, -NRCOO-, -OCONR-, or -NRS02NR'- (wherein R and R' each represents a hydrogen atom, an alkyl group, or an aryl group); and A represents a residue formed by removing one hydrogen atom from Ar of the compound represented by the following general formula (II) or a residue formed by removing M from the compound of general formula (II):
wherein Ar represents an aryl group; M represents a formyl group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a sulfinamoyl group, an alkoxysulfonyl group, a thioacyl group, a thiocarbamoyl group, or a heterocyclic group; R, represents a hydrogen atom; said M, R1 and the nitrogen atom to which M and R1 attach may form a partial structure -N=C≺ of hydrazone; and Ro represents a hydrogen atom, a formyl group, an acyl group, an alkoxy-carbonyl group, or an aryloxycarbonyl group. The silver halide photographic material is capable of having high contrast negative images, high sensitive negative images, and good dot images.
