Reactive dyes which particularly suitable for dyeing or printing cellulose fiber material by the exhaust method or by continuous methods, which produce dyeing having good fastness properties in a high coloristic yield, having the formula <IMAGE> (1) where 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, R1 and R2 are independently of each other hydrogen or alkyl having 1 to 4 carbon atoms which may be substituted by halogen, hydroxyl, cyano, C1-C4alkoxy, C1-C4alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato, B is a direct bond or a radical -(CH2)-n or -O-(CH2)-n, n is 1, 2, 3, 4, 5 or 6, R is a radical of the formula <IMAGE> (2a) <IMAGE> (2b) <IMAGE> (2c) <IMAGE> (2d) <IMAGE> (2e) or <IMAGE> (2f) where R' is hydrogen or C1-C6alkyl, alk is alkylene having 1 to 7 carbon atoms or a branched isomer thereof, T is hydrogen, halogen, hydroxyl, sulfato, carboxyl, cyano, C2-C4alkanoyloxy, C1-C4alkoxycarbonyl, carbamoyl or a radical -SO2-Z, V is hydrogen, substituted or unsubstituted C1-C4alkyl or a radical of the formula -(alk)-CH2-SO2-Z, where (alk) is as defined above, each alk' is indepedently of the other polymethylene having 2 to 6 carbon atoms or a branched isomer thereof, Z is beta -sulfatoethyl, beta -thiosulfatoethyl, beta -phosphatoethyl, beta -acyloxyethyl, beta -haloethyl or vinyl, p, q, r and t are each independently of the others 1, 2, 3, 4, 5 or 6, s is 2, 3, 4, 5 or 6, and A is a radical of the formula <IMAGE> (3a) or <IMAGE> (3b) where R2, B and R are as defined above, X is a radical -SO2-Z or -N(R3)-SO2Z, where Z is as defined above, and R3 is hydrogen, methyl or ethyl, or where A is a radical which is bonded directly to the triazine ring and has the formula (2a), (2b), (2c), (2d), (2e) or (2f) where R', T, alk, V, alk', Z, p, q, r, s and t are as defined above; if it is a radical of the formula (3a), A can be different from the corresponding radical in the formula (1) which includes the benzene nucleus I, and the benzene nuclei I and II or the benzene or naphthalene nucleus III may contain independently of one another further substituents.
