Water-soluble disazo compounds containing one or two (nitro- phenylamino)- phenylamino-chlorotriazinylamino groups, the nitro- phenylamino being additionally substituted by a fiber-reactive group of the vinylsulfone series, suitable as dyestuffs

摘要

Water-soluble disazo compounds which have fiber-reactive dye properties, which are suitable for dyeing carboxamido- and/or hydroxy- containing materials, in particular cellulose fiber materials, and which contain as bivalent coupling component 1-amino-8-naphthol-3,6- or -4,6- disulfonic acid and as diazo components an optionally substituted phenyl radical or naphthyl radical, one or both of the diazo components possessing a fiber-reactive group of the general formula ##STR1## in which the two R.sup.1, 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 of a sulfo group and Y represents the vinyl group or a -thiosulfatoethyl, -phosphatoethyl, - chloroethyl or -sulfatoethyl group, and it being possible for one of these diazo components also to contain, as substituent in place of this fiber-reactive grouping, a fiber-reactive group of the formula --SO. sub. 2 --Y where Y has the abovementioned meaning.
