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
A reactive yellow dye having the formula
