A silver halide color light-sensitive material having excellent properties for a sensitization treatment is described, containing a polymer coupler having an average molecular weight higher than 30,000 and having a polymeric unit derived from a monomeric magenta coupler represented by formula (I):
wherein R1 is hydrogen, chlorine, or a lower alkyl group having 1 to 4 carbon atoms; A is a phenylene group, a -CONH- group, or a -COO- group; B is an unsubstituted or substituted alkylene group, an unsubstituted or substituted aralkylene group, or an unsubstituted or substituted phenylene group; Y is -0-, -NH-, -S-, -SO-, -S02-, -CONH-, -COO-, -NHCO-, or -NHCONH-; Q is a residue of a magenta color-forming coupler which forms a dye through coupling with the oxidation product of an aromatic primary amine developer; and m is 1 when n is 1, and m is 0 or 1 when n is 0.
本发明描述了一种在敏化处理方面具有优异性能的卤化银彩色感光材料,该材料含有一种平均分子量高于 30,000 的聚合物耦合剂,该聚合物耦合剂具有由式 (I) 所表示的单体品红色耦合剂衍生的聚合物单元:
其中 R1 是氢、氯或具有 1 至 4 个碳原子的低级烷基;A 是亚苯基、-CONH- 基团或 -COO- 基团;B 是未取代或取代的亚烷基、未取代或取代的亚芳烷基或未取代或取代的亚苯基;Y 是-0-、-NH-、-S-、-SO-、-S02-、-CONH-、-COO-、-NHCO-或-NHCONH-; Q 是洋红色成色偶联剂的残留物,该偶联剂通过与芳香族伯胺显色剂的氧化产物偶联形成染料;当 n 为 1 时,m 为 1,当 n 为 0 时,m 为 0 或 1。
