Abstract

Reactive dyes of the formula ##STR1## where l is 0 or 1, PA0 n is 0 or 1, PA0 E is nitrogen or C--Cl PA0 A is the radical of an azo dye attached to the triazine ring via an imino or C.sub.1 -C.sub.4 -alkylimido group, PA0 B--if E is nitrogen--is the radical of an azo dye or of a formazan dye which in either case is bonded to the triazine ring via an imino of C.sub.1 -C.sub.4 -alkylimino group or else--if n is 0--is fluorine, chlorine or unsubstituted or substituted amino, or--if E is C--Cl--is fluorine, chlorine or methyl, PA0 X.sup.1 and X.sup.2 are independently of the other fluorine or chlorine, PA0 X.sup.3 is fluorine or chlorine or else--if E is C--Cl--methylsulfonyl and PA0 Z.sup.1 and Z.sup.2 are independently of the the other a radical of the formula ##STR2## where L.sup.3 and L.sup.4 are independently of the other hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl, PA0 with the proviso that l and n are not simultaneously 0 and that, if E is C--Cl or if n is 0 and Z.sup.1 is the radical of the formula ##STR3## where L.sup.3 and L.sup.4 are each as defined above, A may also be the radical of a formazan dye which is bonded to the triazine ring via an imino or C.…
