Abstract:
Doubled reactive dyes of the general formula I ##STR1## where Chr is a chromophore residue with or without further fiber-reactive groups and derived from a metallized or unmetallized mono- or disazo dye, from a triphendioxazine, from an anthraquinone, from a metallized formazan or from a metallized phthalocyanine,Z.sup.1, Z.sup.2 and Z.sup.3 are each independently of the others hydrogen or substituted or unsubstituted C.sub.1 -C.sub.6 -alkyl,Hal is fluorine or chlorineL.sup.1 and L.sup.2 are each independently of the other C.sub.2 -C.sub.6 -alkylene with or without interruption by 1 or 2 unadjacent oxygen atoms, andA is hydrogen, substituted or unsubstituted C.sub.1 -C.sub.6 -alkyl, substituted or unsubstituted phenyl, substituted or unsubstituted C.sub.2 -C.sub.3 -alkenyl, substituted or unsubstituted C.sub.1 -C.sub.6 -alkoxy, substituted or unsubstituted phenoxy or C.sub.1 -C.sub.6 -alkylamino,and their mixtures are prepared and useful for dyeing or printing hydroxyl-containing or nitrogenous substances.
