    摘要： There is disclosed a light-sensitive material comprising, in a hydrophilic colloid provided on a base, a color-developing agent represented by formula (I) or (II):


            R3-NHNH-Z 2      formula (II)

       wherein Z 1 represents an acyl group, a carbamoyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; Z 2 represents a carbamoyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; X 1 , X 2 , X 3 , X 4 , and X 5 each represent a hydrogen atom or a substituent, provided that the sum of the Hammett substituent constant σp values of X 1 , X 3 , and X 5 and the Hammett substituent constant σm values of X 2 and X 4 is 0.80 or more but 3.80 or below; and R 3 represents a heterocyclic group. There is also disclosed a novel color-developing agent that can be built in. By using the color-developing agent, the light-sensitive material can attain a rapid and simple formation of an image.

    摘要： 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.
