ABSTRACT:
Reactive dyes which are particularly suitable for the dyeing or printing of cellulose-containing fiber materials by the exhaust process or by the continuous process and give, at a high color yield, dyeings and prints having good fastness properties, having the formula ##STR1## in which D.sub.1 and D.sub.2, independently of one another, are each a 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.sub.1, R.sub.2, B.sub.1 and B.sub.2, independently of one another, are hydrogen or alkyl having 1 to 4 carbon atoms, which is unsubstituted or substituted by halogen, hydroxyl, cyano, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato; X is fluorine, chlorine, bromine, sulfo, C.sub.1 -C.sub.4 alkylsulfonyl, phenylsulfonyl or carboxypyridinium, and E is a radical of the formula ##STR2## in which A.sub.1 and A.sub.2, independently of one another, are each a radical of the formula ##STR3## or X is a radical of the formula ##STR4## and E is a radical of the formula (3a), (3b), (3c) or (3d); and R.sub.3 is hydrogen or alkyl having 1 to 4 carbon atoms, which is unsubstituted or substituted by halogen, hydroxyl, cyano, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato; R.sub.4 and R.sub.5, independently of one another, are 0 to 3 substituents from the group consisting of C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, carboxyl and sulfo; B is a direct bond or --(CH.sub.2).sub.n --or --O--(CH2).sub.n --, n is 1 to 6; R is a radical of the formula ##STR5## Z is a .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-acyloxyethyl, .beta.-halogenoethyl or vinyl; alk is alkylene having 1 to 6 carbon atoms or branced isomers thereof; T is hydrogen, chlorine, bromine, fluorine, hydroxyl, sulfato, alkanoyloxy having 2 to 4 carbon atoms, cyano, carboxyl, alkoxycarbonyl having 1 to 5 carbon atoms, carbamoyl, or --SO.sub.2 --Z in which Z is as defined above;
