ABSTRACT:
Preparation of water-soluble reactive dyes containing vinylsulphonyl and .beta.-sulphatoethylsulphonyl groups by the oxidation of dyes containing .beta.-hydroxyethylmercapto radicals, and then sulphation and, if appropriate, conversion of the .beta.-sulphatoethylsulphonyl radical to the vinylsulphonyl radical with bases. Novel fiber-reactive monoazo or disazo dyes of the structure ##STR1## wherein the substituents have the formulae given in the description and a method of coloring polyurethane plastics using dyestuffs of the formula ##STR2## as well as novel monoazo dyestuffs of the formula ##STR3##
