Abstract

Reactive dyes of the formula ##STR1## where n is 0 or 1, PA0 R.sup.1, R.sup.2 and R.sup.3 are each hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl, PA0 A is unsubstituted or substituted C.sub.2 -C.sub.8 -alkylene, PA0 Y is vinyl or a radical of the formula --CH.sub.2 --CH.sub.2 --Q, where PA0 Q is a group which can be eliminated under alkaline reaction conditions, PA0 D.sup.1 is phenyl or naphthyl, where these radicals may be substituted, PA0 D.sup.2 is phenylene or naphthylene, where these radicals may be substituted, and PA0 Z is a reactive radical, with the proviso that PA0 a) n is zero when D.sup.1 is substituted by unsubstituted or substituted phenylazo or by unsubstituted or substituted naphthylazo and PA0 b) the reactive radical Z is not devised from the triazine series when n is zero and D.sup.1 is dihydroxysulfonylphenyl or trihydroxysulfonylnaphthyl, are used for dyeing and printing organic substrates containing hydroxyl groups or nitrogen atoms.
