    摘要： A silver halide photographic material which contains at least one blocked photographic reagent having in the molecule thereof at least one ##STR1## structure and capable of releasing a photogrpahically useful reagent by cleavage of the ##STR2## bond by a nucleophilic attack of a nucleophilic reagent on the structure and a subsequent intramolecular electron transfer reaction or an intramolecular nucleophilic reaction and which has at least one photosensitive silver halide emulsion layer. There is provided a photogrphic 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.

    摘要： A process for stabilizing a silver image is disclosed. The process is utilized in connection with a photographic material which is comprised of a water impermeable support having one or more light-sensitive silver halide emulsion layers thereon. After the photographic material is exposed and developed it is subjected to further processing by conventional means. However, within the further processing an aqueous solution is utilized which includes any compounds represented by the general formula (I), (II) or (III) as defined within the specification. The compound(s) represented by the general formula is/are generally present within the processing solution in a total amount of about 0.1 to 10 g/l of processing solution. By utilizing the aqueous solution containing the compound represented by the general formula within the processing, it is possible to greatly increase the stability of the silver image formed.
