    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.

    摘要： A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer is disclosed, wherein said light- sensitive material contains a DIR coupler represented by formula (I):
    wherein A represents a coupler residue; R represents an alkyl group having from 1 to 4 carbon atoms or a pyridyl group; and n represents 1 when A represents a phenol type or naphthol type coupler residue, or n represents 0 when A represents other coupler residues, and said emulsion layer contains chemically sensitized silver halide grains which individually have a distinct layer comprising silver iodobromide containing from 7 to 45 mol% of silver iodide and which individually have an overall silver iodide content of more than 4 mol%. The photographic material is excellent in sensitivity, graininess, sharpness, color reproducibility, and preservative and is less liable to variation in photographic performance properties even when continuously processed under replenishment.
