Water-soluble azo compounds containing, as fiber-reactive groups, a (nitrophenylamino-phenylamino)-chloro-triazinylamino group and groups of the vinylsulfone series, suitable as dyestuffs

摘要

Water-soluble monoazo and disazo compounds having fiber-reactive dye properties which are suitable for dyeing carbamoyl- and hydroxyl-containing materials, in particular cellulose fiber materials, and containing as diazo components an optionally substituted phenyl radical or naphthyl radical or a phenylazophenyl, phenylazonaphthyl, naphthylazophenyl or naphthylazonaphthyl radical, one of these radicals containing bonded in the diazo component a vinylsulfonyl, beta -thiosulfatoethylsulfonyl, beta -phosphatoethylsulfonyl, beta -chloroethylsulfonyl or beta -sulfatoethylsulfonyl group, and as coupling component that of a naphthol, aminonaphthaline or aminobenzene having a fiber-reactive grouping of the general formula <IMAGE> in which the two R1s, identical to or different from each other, denote a hydrogen atom or an optionally substituted alkyl group of 1 to 4 carbon atoms, R is a hydrogen atom or a sulfo group and Y represents the vinyl group, a beta -thiosulfatoethyl, beta -phosphatoethyl, beta -chloroethyl or beta -sulfatoethyl group.
