ABSTRACT:
Disclosed is a silver halide photographic material comprising a support, having thereon at least one silver halide emulsion layer, wherein there is contained in the silver halide emulsion layer or other hydrophilic colloid layer a compound of which an oxidized form is produced in accordance with development of the silver halide and is capable of releasing a photographically useful group by means of a conjugated addition-elimination mechanism due to an intramolecular nucleophilic group attack.
