Abstract

Water-soluble compounds having fiber-reactive dye properties of the general formula ##STR1## in which A is an alkylene of 2 to 6 carbon atoms or a phenylene which can be substituted by 1 or 2 substituents, or is a radical of the formula ##STR2## in which W is a direct bond or a bridge member and the R' and R* each denote hydrogen, chlorine, methyl, methoxy, ethoxy, carboxy or sulfo; PA1 B is chlorine or fluorine; PA1 R is hydrogen, chlorine, an alkyl of 1 to 4 carbon atoms or an alkoxy of 1 to 4 carbon atoms; PA1 M is hydrogen or an alkali metal; PA1 n stands for the number zero, 1 or 2, PA1 K is a radical of the formula ##STR3## in which D is phenylene which can be substituted by chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxy or sulfo, or is naphthalene with optionally 1 or 2 sulfo groups, PA1 R.sup.1 denotes hydrogen, chlorine, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms, PA1 R.sup.2 is hydrogen or alkyl of 1 to 4 carbon atoms, PA1 G is carboxy, methyl or carbalkoxy of 2 to 5 carbon atoms, PA1 Y denotes vinyl, .beta.-sulfatoethyl, .beta.-phosphatoethyl, .beta.-thiosulfatoethyl or .beta.-chloroethyl, PA1 Z is the .alpha.- …
