Water-soluble azo compounds containing a sulfo-naphthol as a coupling component and having fiber-reactive groups of the vinylsulfone series, suitable as dyestuffs

摘要

Water-soluble azo compounds which have fiber-reactive dyestuff properties and dye materials containing carboxamide and/or hydroxyl groups, such as fiber materials, in particular cellulose fiber materials, in strong, fast, predominantly bluish-tinged red to orange shades; they correspond to the general formula (1) ##STR1## in which: M is a hydrogen atom or an alkali metal;PPR is alkyl having 1 to 4 carbon atoms;PPD is a group of the formula ##STR2## in which R. sup.1 is hydrogen, alkyl having 1 to 4 carbon atoms, hydroxy, nitro, alkoxy having 1 to 4 carbon atoms, chlorine, bromine or carboxy, R.sup.2 is hydrogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, chlorine or sulfo,PPR.sup.3 is hydrogen or sulfo;PPk is the number zero or 1;PPp is the number zero, 1 or 2;PPm is the number zero or 1; PPn is the number zero or 1; andPPX and Y are both independently of one another vinyl, -thiosulfatoethyl or - sulfatoethyl.
