Water-soluble copper complex disazo compounds containg a chloro triazinylamino group and a group of the vinylsulfone series as fiber-reactive groups and their dyestuffs

Abstract

Water-soluble copper complex disazo compounds with fiber-reactive dyestuff properties of the general formula ##STR1## in which m and n are the number zero or 1; the group --SO.sub.2 Y is bonded in the 5-position to the benzene nucleus if n is zero, or in the 4-position if n is zero or 1; the free azo can be bonded to the 6'-or 7'-position of the central naphthalene nucleus; if m is 1, this sulfo is bonded in the 5'-position if the azo is in the 6'-position, and is bonded in the 6'-position if the azo is in the 7'-position; X is chlorine, bromine, ##STR2## in which R.sup.1 represents optionally substituted alkyl with 1 to 4 carbon atoms, optionally substituted aryl or hydrogen, R.sup.2 is optionally substituted alkyl with 1 to 4 carbon atoms or optionally substituted aryl, R.sup.3 is hydrogen or optionally substituted alkyl with 1 to 4 carbon atoms and R.sup.4 is hydrogen, cycloalkyl which is optionally subsituted by 1 to 3 methyl, optionally substituted alkyl with 1 to 4 carbon atoms or optionally substituted aryl, or R.sup.3 and R.sup.4, as alkylene radicals with 1 to 4 carbon atoms together with the nitrogen atom and optionally an oxygen, sulfur or nitrogen atom as a further hetero-atom, form a heterocyclic six-membered radical; Y is vinyl or of the formula --CH.sub.2 --CH.sub.2 --R in which R is a radical which can be eliminated under alkaline conditions; and M is hydrogen or the equivalent of a metal.
