ABSTRACT:
Water-soluble disazo compounds of the general formula ##STR1## in which D.sub.1 and D.sub.2 are each a phenylene or naphthylene radical which can be substituted by 1 or 2 substituents from the group consisting of 1 chlorine, 1 bromine, 2 sulfo, 2 carboxyl, 2 alkyl of 1 to 4 carbon atoms and 2 alkoxy of 1 to 4 carbon atoms, R' and R" each denote an amino or hydroxyl group, R.sup.+ and R* each represent methyl, carboxyl or lower carbalkoxy, R.sup.1 and R.sup.3 are each hydrogen, lower alkyl, lower alkoxy, chlorine or bromine, R.sup.2 and R.sup.4 each denote hydrogen, lower alkyl, lower alkoxy or chlorine, X denotes a vinyl, .beta.-sulfatoethyl,.beta.-thiosulfatoethyl or .beta.-chloroethyl group and Y is a chlorine, fluorine or bromine atom or a sulfo, hydroxyl, aliphatic or aromatic ether group or thioether group or a primary, secondary or tertiary amino group. These disazo compounds have fiber-reactive dyestuff properties and produce on hydroxyl- and/or carboxamide-containing material, in particular fiber material, such as cellulosic fibers, strong dyeings having good fastness properties.
