ABSTRACT:
Reactive dyes of the formula ##STR1## are particularly suitable for dyeing or printing cellulosic fibre materials by the exhaust method or by continuous processes and give, with a high color yield, dyeings and prints with good fastness properties, in which D is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dye; R is hydrogen or alkyl having 1 to 4 carbon atoms, which can be substituted by hydroxyl, cyano, carboxyl, sulfo or sulfato; X is fluorine or chlorine; B is a substituted or unsubstituted aliphatic or aromatic bridge member; Y is a substituted or unsubstituted aliphatic, aromatic, araliphatic or heterocyclic radical, which is free from reactive groups; R.sub.2 is hydrogen or alkyl having 1 to 4 carbon atoms, which can be substituted by halogen, hydroxyl, cyano, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkoxycarbonyl, carboxyl, carbamoyl, sulfamoyl, sulfo or sulfato; and R.sub.1, independently of R.sub.2, has the same meaning as R.sub.2 or is a radical of the formula ##STR2## in which B, Y and R.sub.2 are as defined under formula (1), independently of these meanings.
