Abstract:
A reactive dye of the formula I ##STR432##wherea is 1 or 2,b is 0 or 1,Y is vinyl or a radical of the formula C.sub.2 H.sub.4 Q, where Q is an alkali-detachable group,Het is the radical of a 5- or 6-membered aromatic heterocyclic ring having from 1 to 3 hetero atoms selected from the group consisting of oxygen, sulfur and nitrogen,W is either,in case 1) the radical of a coupling component, of a monoazo dye or additionally, when b=0, of a disazo dye, which may each bear further fiber-reactive groups, orin case 2) the radical of a chromophore which optionally has further fiber-reactive groups and is derived from an optionally metallized mono- or disazo dye, a triphendioxazine, an anthraquinone, a metallized formazan or a metallized phthalocyanine,L.sup.1 is either, in case 1), an azo bridge or,in case 2), a bridge member of the formula O.sub.2 S--NZ.sup.1, OC--NZ.sup.1, Z.sup.1 N--SO.sub.2, Z.sup.1 N--CO, Z.sup.1 N--CO--NZ.sup.2, NZ.sup.1 or ##STR433##where Z.sup.1 and Z.sup.2 are independently of each other hydrogen, C.sub.1 -C.sub.6 -alkyl or phenyl and Hal is fluorine, chlorine or bromine, or NZ.sup.1 or NZ.sup.2 also represents 1,4-piperazinediyl,L.sup.2 is a radical of the formula ##STR434##where Z.sup.3, Z.sup.4, Z.sup.5 and Z.sup.6 are each independently of the others hydrogen, C.sub.1 -C.sub.6 -alkyl or phenyl, L.sup.4 is C.sub.2 -C.sub.8 -alkylene or unsubstituted or C.sub.1 -C.sub.4 -alkyl-, C.sub.1 -C.sub.4 -alkoxy- or hydroxysulfonyl-substituted phenylene, and Hal is in each case as defined above,L.sup.3 is a direct bond or C.sub.1 -C.sub.6 -alkylene with or without interruption by 1 or 2 oxygen or sulfur atoms in ether function or 1 or 2 unadjacent imino, C.sub.1 -C.sub.4 -alkylimino or C.sub.1 -C.sub.4 -alkanoylimino groups, andA.sup.1 and A.sup.2 are independently of each other hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen, nitro, amino, hydroxysulfonyl or a radical of the formula L.sup.3 --SO.sub.2 --Y, where L.sup.3 and Y are each as defined above.
