ABSTRACT:
Reactive dyes of the formula ##STR1## in which R.sub.1, R.sub.2 and R.sub.3, independently of one another, are C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, ureido, C.sub.1 -C.sub.4 acylamino, carboxyl and sulfo and n, m and p, independently of one another, are the number 0, 1, 2 or 3, X is fluorine or chorine and Z is an aliphatic, araliphatic, aromatic or heterocyclic amino group free from fibre-reactive radicals; or Z is the radical of an aliphatic or aromatic diamine which contains the radical of the formula ##STR2## in which R.sub.1, R.sub.2, R.sub.3, n, m, p and X are as defined, bound via the second amino group; or Z is a radical of the formula ##STR3## in which R.sub.1, R.sub.2, R.sub.3, n, m, and p are as defined; or Z is a radical --NH--SO.sub.2 --(CH.sub.2).sub.2 --OSO.sub.3 H; and the reactive dye of the formula (1) contains at least two sulfo groups, produce, on cellulose fibres, orange dyeings of high color strength and prints of good fastness properties.
