DYE MIXTURE OF FIBER REACTIVE AZO DYES, METHOD FOR PREPARING THE SAME, AND METHOD FOR DYEING HYDROXY-AND/ OR CARBOXAMIDE-CONTAINING MATERIAL BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a yellow-orange mixture of fiber reactive azo dyes and a method for dyeing a hydroxy- or carboxamide-containing fiber material by using the same. SOLUTION: There are provided a dye mixture comprising at least one disazo dye represented by formula 1 and at least one azo dye represented by formula 2, a method for preparing the same, and a method for dyeing a hydroxy- and/or carboxamide-containing fiber material by using the same: (wherein R1 and R2 are each hydrogen, sulfo or the like; R3 and R4 are each a 1-4C alkyl, phenyl or the like; Y1 and Y2 are each vinyl, or ethyl that fonns a vinyl group by the action of an alkali; M is hydrogen or an alkali metal; B is a group of 4-(B-sulfatoethylsulfonyl)phenyl or the like; and K is a coupling component of 2'-methoxy-5'-methyl-4'-sulfoacetoanilide or the like).
