ABSTRACT:
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.
