    摘要: Reactive dyestuffs of the formulaD-(T).sub.mwhereinD=the radical of an organic dyestuff,m=1-4 andT= ##STR1## wherein X and Y=a direct bond or a bridge member,W= ##STR2## acyl=an acyl radical and R.sub.1 -R.sub.3 =H, alkyl or aralkyl,the radical T being bonded, via X, to a C atom of an aromatic-carbocyclic or aromatic-heterocyclic ring of the chromophore and their use for dyeing and printing textile materials containing hydroxyl groups and textile materials containing nitrogen. The dyeings obtained are distinguished by good fastness properties, in particular excellent fastness to wet processing.
