摘要:
A silver halide photographic material having on a support at least one silver halide emulsion layer, which contains at least one precursor of the kind which releases at least two groups selected from the group consisting of a photographically useful group and a precursor thereof via a timing group, wherein plural photographically useful groups or precursors thereof are present on different constituent atoms of said timing group, provided that when the plural photographically useful groups have different functions, the timing group is a group which does not utilize an intramolecular nucleophilic substitution reaction.
