Cyan-forming colour couplers according to the formula:
wherein Z is hydrogen in the case of4-equivalent couplers or a substituent that splits off upon colour development, thus conferring a 2-equivalent character to the colour coupler, and Y is a ballasting group. These cyan-forming colour couplers can be incorporated in (a) red-sensitized silver halide emulsion layer(s) of a photographic multilayer colour element or in a non-light-sensitive colloid layer in water-permeable relationship with the red-sensitized emulsion layer(s).
根据式子的发青颜色耦合剂:
其中 Z 在 4 等价耦合剂的情况下是氢,或在显色时会分裂的取代基,从而使颜色耦合剂具有 2 等价的特性,Y 是压载基团。这些形成青色的颜色耦合剂可以加入摄影多层彩色元件的(a)红色感光卤化银乳剂层中,或加入与红色感光乳剂层有透水性关系的非感光胶体层中。
