A photographic element comprises novel pyrazolo[5,1-c]-1,2,4-triazole dye forming couplers, the couplers and azomethine dyes. The couplers are represented by the following structure:
wherein:
Z represents the elements of C, N, O, or S necessary to complete a substituted or unsubstituted heterocyclic 5 or 6 member ring along with nitrogen;
R1 represents a substituent group;
and, X represents a hydrogen or a coupling off group.
一种感光元件包括新型吡唑并[5,1-c]-1,2,4-三唑染料形成耦合剂、耦合剂和偶氮甲基染料。耦合剂由以下结构表示:
其中
Z代表C、N、O或S元素,这些元素与氮一起组成一个取代或未取代的杂环5或6成员环;
R1 代表取代基;
X 代表氢或偶联基团。
