ABSTRACT:
Novel reactive dyes of the formula ##STR1## in which Z is a radical of the formula ##STR2## in which R.sub.1 and R.sub.2 independently of one another are hydrogen or C.sub.1 -C.sub.6 alkyl, which can be substituted by C.sub.1 -C.sub.4 alkoxy, hydroxy-C.sub.1 -C.sub.4 alkoxy, HO--(CH.sub.2 CH.sub.2 --O).sub.2-4 --, C.sub.1 -C.sub.4 alkoxy-carbonyl, C.sub.2 -C.sub.4 alkanoyloxy, carboxyl, cyano, chlorine, sulfo or sulfato, n is the number 0, 1 or 2 and m is the number 1 or 2, (Q.sub.1).sub.m is 1 or 2 substituents Q.sub.1 independent of one another from the group comprising C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, acetylamino and carboxyl, (Q.sub.2).sub.n is 0 to 2 substituents Q.sub.2 and (Q.sub.2).sub.m is 1 or 2 substituents Q.sub.2 independent of one another from the group comprising C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, acetylamino, halogen and carboxyl, and the sulfo group in the radical of the formula (1b) is bonded to the benzene ring in the 3- or 4-position, give deep scarlet red dyeings and prints with good fastness properties on cellulose fibres.
