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

摘要： A MONOAZO DYE OF THE FORMULA, AS A FREE ACID

1-(H0-),2-(HO3S-O-CH2-CH2-SO2-A-N=N-),3-(HO3S-),6-Y,7-X-

NAPHTHALENE

WHEREIN A IS A BENZENE RING UNSUBSTITUTED OR SUBSTITUTED WITH A LOWER ALKYL GROUP, A LOWER ALKOXY GROUP OR A HALOGEN ATOM AND ONE OF X AND Y IS HYDROGEN ATOM AND THE OTHER IS

WHEREIN X AND Y ARE AS DEFINED ABOVE, AND TREATING THE RESULTANT HAVING B-HYDROXYETHYL SULFONYL GROUP WITH A SULFATING AGENT. THE DYE MAY BE USED FOR DIP-, PAD-DYEING OR PRINTING TEXTILE FIBERS.

1-(HO-),3-(HO3S-),6-Y,7-X-NAPHTHALENE

WHEREIN A IS AS DEFINED ABOVE AND Z IS HYDROXY GROUP OR -OSO3H, WITH AN A-NAPHTHOL DERIVATIVE HAVING THE FORMULA,

ZCH2CH2SO2-A-NH2

THE DYE IS PRODUCED BY REACTING A DIAZOTIZED AMINE HAVING THE FORMULA,

-NHCOCH=CHCOOH

OR

-NHCOCH2CH2COOH
