ABSTRACT:
Reactive dyes of the formula ##STR1## 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, C.sub.1- C.sub.4 alkoxy or halogen; B is a radical --CH.sub.2n, --O--CH.sub.2n or --NH --CH.sub.2n and n is 1 to 6; R is a radical of the formula ##STR2## 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 --SO.sub.2 --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 ##STR3## in which Z, alk and Y are as defined above; R.sub.1 is hydrogen or C.sub.1 -C.sub.6 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.
