Reactive dyes suitable in particular for dyeing or printing cellulose-containing fiber materials by the exhaust method or by continuous methods and, while giving a high dyeing yield, produce dyes and prints having good fastness properties; having the formula <IMAGE> (1) in which D is the radical or a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thiozanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dye, R, B1 and B2 are independently of each other hydrogen or alkyl which has 1 to 4 carbon atoms and which can be substituted by halogen, hydroxyl, cyano, C1-C4-alkoxy, C1-C4alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato, X and Y independently of each other are fluorine, chlorine, bromine, sulfo C1-C4alkylsulfonyl or phenylsulfonyl, A is an amino substituent which contains at least one group of the formula -SO2-Z (2) z is beta -sulfatoethyl, beta -thiosulfatoethyl, beta -phosphatoethyl, beta -acyloxyethyl, beta -haloethyl or vinyl, and Q is 1 or 2 substituents from the group consisting of hydrogen, C1-C4alkyl, (1), wherein D is phthalocyanine and Y is fluorine.
