A novel silver halide photographic material is provided comprising a support and at least one silver halide photographic emulsion layer formed thereon and containing in said photographic emulsion layer or at least one hydrophilic colloid layer a compound represented by formula (I): <IMAGE> (I) wherein R1 and R2 may be the same or different and each represents a hydrogen atom, an aliphatic residual group, an aromatic residual group, or a heterocyclic residual group; R3 represents a hydrogen atom or an aliphatic residual group; L1 represents a divalent aliphatic group, a divalent aromatic group, or a divalent heterocyclic group; L2 represents -O-, -CONR-, -NRCO-, -SO2NR-, -NRSO2-, -OCO-, -COO-, -S-, -NR-, -CO-, -SO-, -SO2-, -OCOO-, -NRCONR'-, -NRCOO-, -OCONR-, or -NRSO2NR'- (in which R and R' each represents a hydrogen atom, an alkyl group or an aryl group); l and m each represents an integer of 1 or 2; n represents an integer of 0 or 1; and A represents a residual group which is obtained by removing hydrogen atoms from Ar or B in a compound represented by formula (II), provided that when m=1, one hydrogen atom is removed; when m=2, two hydrogen atoms are removed: <IMAGE> (II) wherein Ar represents an aryl group; B represents a formyl group, an acyl group, an alkyl or arylsulfonyl group, an alkyl or arylsulfinyl group, a carbamoyl group, a sulfamoyl group, an alkoxy or aryloxycarbonyl group, a sulfinamoyl group, an alkoxysulfonyl group, a thioacyl group, a thiocarbamoyl group, or a heterocyclic group; and R0 and R00 each represents a hydrogen atom or one of R0 and R00 represents a hydrogen atom and the other represents a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group or a substituted or unsubstituted acyl group, with the proviso that B, R00 and the nitrogen atom to which B and R00 are bonded may together form a partial structure of hydrazone (-N=C<).
