Beschreibung
Zusammenfassung:	Reactive dyes of the formula where n is 0 or 1, R , R and R are each hydrogen, C1-C4-alkyl or phenyl, R is fluorine, chlorine, bromine, C1-C4-alkylsulphonyl, phenylsulphonyl, or a radical of the formula L is a bridge member, A is substituted or unsubstituted C2-C8-alkylene, Y is vinyl or a radical of the formula -CH2-CH2-Q, where Q is a group which is detachable under alkaline reaction conditions, and D is phenyl or naphthyl, which can each be substituted, and a process for producing reactive dyes by oxidation of the abovementioned compounds.
