    • A dye-forming coupler of formula (I), a silver halide photographic light-sensitive material containing the coupler, and an azomethine dye compound derived from the coupler: wherein Q is a residue that forms, together with the —N—C═N— moiety, a nitrogen-containing 6-membered ring; RA is a certain alkyl group having at least 7 carbon atoms, or -L-R1; X is an aryl group; Y is a hydrogen atom, or a group capable of being split-off upon a coupling reaction; wherein, when RA is -L-R1, L is a divalent linking group, and R1 is a substituent; and -L-R1 does not represent an alkyl, alkenyl, alkynyl, or aryl group, and -L-R1 does not represent a heterocyclic group that bonds, with a carbon atom therein, to the nitrogen atom of the nitrogen-containing 6-membered ring formed by Q and the —N—C═N— moiety.
    • 式(I)的染料成色剂,含有偶合剂的卤化银摄影感光材料和衍生自成色剂的偶氮甲碱染料化合物:其中Q是与-NCN-部分一起形成的残基, 含氮6元环; R A A是具有至少7个碳原子的某一个烷基,或者是-L-R 1; X是芳基; Y是氢原子,或在偶合反应时能够分离的基团; 其中当R A A为-L-R 1时,L为二价连接基团,R 1为取代基; 并且-LR 1不表示烷基,烯基,炔基或芳基,并且-LR 1不表示与其中的碳原子键合的杂环基团 到由Q和-NCN-部分形成的含氮6元环的氮原子。
