ABSTRACT:
Disclosed is a silver halide photographic material comprising a support having thereon at least one layer containing a compound represented by general formula (I): ##STR1## wherein EAG represents an electron-accepting group; A represents a group which undergoes a reaction triggered by the cleavage of the oxygen-nitrogen single bond in the general formula to release PUG; B represents a hydrogen atom or an alkyl group, an aralkyl group, an aryl group, a heterocylic group, an acyl group, a sulfonyl group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkoxysulfonyl group or an aryloxysulfonyl group which may contain substituents; the solid lines indicate a single bond; the broken lines indicate that either of these line is a bond, with the proviso that when the broken line between N and A represents a bond, B is not present; EAG and B, and A and B may be connected to each other to form a ring; EAG may be connected to a polymer residue to fix the compound of general formula (I) to a high molecular chain; n represents an integer 0 or 1; and PUG represents a photographically useful group, with the proviso that when n is 0, PUG represents a photographically useful group represented by general formula (II); ##STR2## wherein X and Y each represents an atom or atomic group required to render the group represented by general formula (II) photographically useful; the solid lines indicate a single bond; and the broken line indicate that either of these lines is a bond, with the provision that X and Y may be connected to each other to form a heterocyclic group containing N and when the broken line between N and X represents a bond, Y is not present.
