摘要:
A silver halide photographic material having on a support, at least one photosensitive silver halide emulsion layer, which contains a coupler which releases at least two groups selected from the group consisting of a photographically useful group and a precursor thereof via a timing group upon undergoing a coupling reaction with an oxidized product of a developing agent, in which a plurality of photographically useful groups or precursors thereof are present on different atoms of the timing group, provided that when the plurality of photographically useful groups have a different function to each other, the timing group is not a group utilizing an intramolecular nucleophilic substitution reaction.
