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.
本发明公开了一种卤化
银彩色感光材料,该材料包括一个在其上具有至少一个感光卤化
银乳剂层的支撑体,其中所述感光材料含有由式(I)表示的DIR耦合剂:
其中,A 代表耦合剂残基;R 代表具有 1 至 4 个碳原子的烷基或
吡啶基;当 A 代表
苯酚型或
萘酚型耦合剂残基时,n 代表 1;当 A 代表其他耦合剂残基时,n 代表 0;所述乳剂层包含
化学感光的卤化
银颗粒,这些颗粒各自具有由
碘溴化银组成的独特层,其中
碘化银的含量为 7 至 45 摩尔%,且各自的总体
碘化银含量超过 4 摩尔%。这种感光材料在感光度、颗粒度、清晰度、色彩再现性和防腐性方面都非常出色,即使在不断补充的情况下进行处理,其感光性能也不易发生变化。
