摘要：
Reactive dyestuffs have the following formula ##STR1## in which D is the radical of an organic dyestuffB is a direct bond or a bridging member on a ring C atom of an aromatic-carbocyclic or on a ring C atom or N atom of an aromatic-heterocyclic ring in D,R.sub.a, R.sub.b, identical or different, are H, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkyl substituted by OH, CN, CO.sub.2 H, OSO.sub.3 H or SO.sub.3 H,U is Cl, F or a pyridinium radical which is unsubstituted or substituted by CO.sub.2 H, CONH.sub.2, SO.sub.3 H or C.sub.1 -C.sub.4 -alkyl,W is straight-chain or branched C.sub.1 -C.sub.6 -alkylene,Y is CH.dbd.CH.sub.2 or CH.sub.2 --CH.sub.2 --X, in whichX is a radical which can be eliminated by alkali,V is H, halogen, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.3 -alkyl, CN, COOH, CONH.sub.2, SO.sub.3 H.
