    摘要： WHEREIN THE BENZENE NUCLEUS A means the same as above; and thereafter treating the resulting mono-azo dye having a hydroxy group as Y in the formula II with sulfuric acid to convert the Beta -hydroxyethyl sulfone group to Beta -sulfatoethylsulfonyl group, and may be used for dyeing fibers a bright yellow shade with excellent fastness to light and washing.

    WHEREIN EACH X1 and X2 mean the same as above and Y represents a hydroxy group or -OSO3H group with 1-substituted phenyl-3-methyl5-amino-pyrazole represented by the formula

    WHEREIN X1 and X2 can each represent hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a carboxyl group, or a sulfonic acid group, and the nucleus A has at least one sulfonic acid group, and may have other substituents, is prepared by coupling a diazotized amine represented by the formula

    摘要： A methine compound of the formula,

    which is a useful intermediate for the production of a yellow coumarine dye of the formula

    The methine compound is prepared by condensing an aldehyde derivative of the formula

    with a compound of the formula X-CH2-Y. The yellow coumarine dye is prepared by condensing the methine compound with one of the following:

    Each of the R1 and R2 is hydrogen, substituted or unsubstituted alkyl or cycloalkyl, or R1 and R2 may form a heterocyclic ring together with the nitrogen atom and other atoms; X is cyano, carbamoyl, carboalkoxy or carboxylic acid; and Y is carbamoyl or cyano, and A is a benzene or naphthalene ring which may be substituted.
