Reactive dyes of the formula <IMAGE> (1) <IMAGE> in which R1, R2 and R3, independently of one another, are C1-C4alkyl, C1-C4alkoxy, halogen, ureido, C1-C4acylamino, 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 <IMAGE> (2) <IMAGE> in which R1, R2, R3, n, m, p and X are as defined, bound via the second amino group; or Z is a radical of the formula <IMAGE> (2a) in which R1, R2, R3, n, m, and p are as defined; or Z is a radical -NH-SO2-(CH2)2-OSO3H; 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.
