摘要： Colored cyan couplers corresponding to formula II are eminently suitable for masking the yellow secondary density of cyan dyes. The reproduction of blues and yellows is thus improved. The colored cyan couplers of formula II are preferably used together with phenolic cyan couplers bearing a phenylureido group in the 2-position and an acylamino group with a ballast group in the 5-position ##STR1## In formula II: CC represents a cyan coupler group to the coupling position of which L is attached;L is a bifunctional connecting group;Q.sup.1, Q.sup.2 represent H or photographially inert substituents;R represents a coupling component such that the compound of formula II is a yellow dye. ##STR2## in which R.sup.3 is alkyl, aryl, carboxyl, carbamoyl, acylamino, anilino;R.sup.4 is H, alkyl, aryl, a heterocyclic group;R.sup.5, R.sup.6 (same or different) represent -CO-alkyl, -CO-aryl, -CO-alkoxy, carbamoyl, -CN;represents O, S, NH;Z is the group required to complete a 5- or 6-membered carbocyclic or heterocyclic ring.

摘要翻译： 对应于式II的着色青色成色剂特别适用于掩蔽青色染料的黄色二次密度。 因此，蓝调和黄色的再现被改善。 式II的着色青色成色剂优选与在2-位上带有苯基脲基的酚蓝色成色剂一起使用，并且在5位上具有镇流剂基团的酰氨基。在式II中：CC表示青色成色剂 组合到其所连接的联接位置; L是双功能连接组; Q1，Q2表示H或照相惰性取代基; R表示偶联组分，使式II化合物为黄色染料。 其中R3是烷基，芳基，羧基，氨基甲酰基，酰基氨基，苯胺基; R4是H，烷基，芳基，杂环基; R5，R6（相同或不同）表示-CO-烷基，-CO-芳基，-CO-烷氧基，氨基甲酰基，-CN; 表示O，S，NH; Z是完成5-或6-元碳环或杂环所需的基团。
