Abstract

Triphendioxazine dyes suitable for dyeing or printing hydroxyl- or amido-containing substrates have the formula ##STR1## where n is 0 or 1, PA1 m is 1 or 2, PA1 R.sup.1 and R.sup.2 are each independently of the other hydrogen, chlorine, bromine, hydroxysulfonyl, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, substituted or unsubstituted phenyl or substituted or unsubstituted phenoxy, PA1 R.sup.3 is halogen, carboxyl, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, vinylsulfonyl or the radical --SO.sub.2 --CH.sub.2 CH.sub.2 --Z, where Z is a leaving group, and PA1 Q.sup.1 and Q.sup.2 are each independently of the other a radical of the formula ##STR2## where R.sup.4 and R.sup.5 are each independently of the other hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl, PA1 R.sup.6 is hydrogen or a fiber-reactive radical, PA1 L.sup.1 and L.sup.2 are each independently of the other substituted or unsubstituted C.sub.2 -C.sub.8 -alkylene or phenylene, PA1 X is a chemical bond, oxygen, sulfur, imino, C.sub.1 -C.sub.4 -alkylimino, carbonyl or methylene, and PA1 Y is oxygen or sulfur, with the proviso that if n is 0, R.sup.6 is a fiber-reactive radical, and that the hydroxysulfonyl groups are …
