Abstract
There are described water-soluble fiber-reactive dye-stuffs which possess a triazinylamino radical to which is bonded as second substituent an amino group or an N-containing heterocyclic group which, bonded via an arylene, alkylene or aralkyl radical, possesses a fiber-reactive grouping of the vinyl sulfone series, and to which is bonded as third substituent a sulfonamide group, wherein the sulfone radical is substituted by optionally substituted aryl, alkylenearyl or arylenealkyl or optionally substituted amino groups. The dyestuffs are used for dyeing hydroxy - and/or carboxamido-containing material, in particular fiber material, such as cellulose fibers, wool and synthetic polyamide.
