Silver halide photographic materials comprising blocked photographic
reagants releasing plug groups
摘要:
A silver halide photographic material, which contains at least one blocked photographic reagent having in the molecule thereof at least one group selected from ##STR1## group and capable of releasing a photographically useful reagent by cleavage of the --N--C--bond by a nucleophilic attack of a nucleophilic reagent on the carbonyl group and a subsequent intramolecular electron transfer reaction or intramolecular nucleophilic reaction and which has at least one photosensitive silver halide emulsion layer, is photographically processed in the presence of an amine. A photographic material which includes, in combination, a photographic reagent precursor capable of releasing a photographically useful reagent timely on photographic processing and a photosensitive silver halide emulsion layer is provided along with a method of processing the photographic material.
