A silver halide color photographic sensitive material is disclosed. The material is comprised of a substrate having a silver halide emulsion layer position thereon and a cyan dye forming coubler. The coupler is represented by the general formula (I):
wherein R represents a substituted or nonsubstituted alkyl group, aryl group or heterocyclic group, X represents a group capable of releasing by an oxidative coupling reaction with a developing agent, and R' represents a substituted or nonsubstituted alkyl group or aryl group. The coupler of the invention can be easily dissolved in a high boiling point organic solvent and makes possible production of a light sensitive material having a high dye forming rate, high maximum color density and good fastness to light. Furthermore, the couplers prevent a large decrease in density when the bleaching solution utilized has a weak oxidation ability.
本发明公开了一种卤化
银彩色感光材料。 该材料由基底和青色
染料形成耦合剂组成,基底上有卤化
银乳剂层,耦合剂由通式(I)表示:其中 R 代表取代或未取代的烷基、芳基或杂环基,X 代表能与显影剂发生氧化偶联反应而释放的基团,R'代表取代或未取代的烷基或芳基。 本发明的耦合剂易于溶解在高沸点有机溶剂中,因此可以生产出
染料形成率高、最大色密度高和耐光牢度好的感光材料。 此外,当使用的漂白溶液氧化能力较弱时,耦合剂可防止密度大幅下降。
