Reactive dyes of the formula <IMAGE> (1) in which D is the radial of an anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dye; Q is hydrogen or alkyl which has 1 to 4 carbon atoms and can be substituted by carboxyl, sulfo, cyano, hydroxyl, C1-C4 alkoxy or halogen; B is a radical -CH2n, -O-CH2n or -NH -CH2n and n is 1 to 6; R is a radical of the formula <IMAGE> (1a) <IMAGE> (1b) <IMAGE> (1c) or <IMAGE> (1d) Z is beta -sulfatoethyl, beta -thiosulfatoethyl, beta -phosphatoethyl, beta -acyloxyethyl, beta -halogenoethyl or vinyl; alk is an alkylene radical having 1 to 6 C atoms or branched isomers thereof; Y is hydrogen, chlorine, bromine, flourine, hydroxyl, sulfato, acyloxy having 1 to 4 C atoms, cyano, carboxyl, alkoxycarbonyl having 1 to 5 C atoms, carbamoyl or a radical -SO2-Z in which Z is as defined above; V is hydrogen or an alkyl radical which has 1 to 4 C atoms and can be substituted by carboxyl or sulfo groups or by derivatives thereof, alkoxy groups having 1 or 2 C atoms, halogen or hydroxyl; or is a radical <IMAGE> in which Z, alk and Y are as defined above; R1 is hydrogen or C1-C6 alkyl; the alk's independently of one another are polymethylene radicals having 2 to 6 C atoms or branched isomers thereof; m is 1 to 6, p is 1 to 6 and q is 1 to 6; and the benzene or naphthalene radical A can contain further substituents, are particularly suitable for dyeing or printing cellulose-containing fibre materials by the cold pad-batch process, and produce, at a high dye yield, dyeings and prints which have good fastness properties.
