A dye-forming coupler of the formula (I). A silver halide photographic light-sensitive material that contains at least one dye-forming coupler of the formula (I). A method for producing an azomethine dye, which method comprises using a compound of the formula (I):
wherein E is an aryl, heterocyclic, or -C(=O)W group, in which W is a nitrogen-containing heterocyclic group, Z is an aryl or heterocyclic group, and X and Y each independently are =O, =S or =N-R, in which R is a substituent, with the proviso that when E is an aryl or heterocyclic group, X and Y each are =O, and that when E is a -C(=O)W group, Z is a substituted aryl group.
式(I)的染料形成耦合剂。一种含有至少一种式(I)染料形成耦合剂的卤化银感光材料。一种生产偶氮染料的方法,该方法包括使用式(I)化合物:
其中 E 是芳基、杂环基或-C(=O)W 基,其中 W 是含氮杂环基,Z 是芳基或杂环基,X 和 Y 各自独立地是=O、=S 或=N-R,其中 R 是取代基,但条件是当 E 是芳基或杂环基时,X 和 Y 各自是=O,当 E 是-C(=O)W 基时,Z 是取代的芳基。
