Abstract
Reactive dyes of the formula ##STR1## in which D is the radical of a dye of the monoazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide series, R.sub.1 is hydrogen or an unsubstituted or substituted C.sub.1-4 -alkyl radical, and X is the vinyl, .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-chloroethyl or .beta.-acetoxyethyl group, are suitable in particular for dyeing and printing cellulose-containing fibre materials by the cold pad-batch method and produce, in high dyeing yields, dyeings and prints having good fastness properties.
