TRIPHENEDIOXAZINE DYE

Triphendioxazine dyes suitable for dyeing or printing hydroxyl- or amido-containing substrates have the formula where n is 0 or 1, m is 1 or 2, R1 and R2 are each independently of the other hydrogen, chlorine, bromine, hydroxysulfonyl, C1-C4-alkyl, C1-C4-alkoxy, substituted or unsubstituted phenyl or substituted or unsubstituted phenoxy, R3 is halogen, carboxyl, C1-C4-alkyl, C1-C4-alkoxy, vinylsulfonyl or the radical -SO2-CH2CH2-Z, where Z is a leaving group, and Q1 and Q2 are each independently of the other a radical of the formula where R4 and R5 are each independently of the other hydrogen, C1-C4-alkyl or phenyl, R6 is hydrogen or a fiber-reactive radical, L1 and L2 are each independently of the other substituted or unsubstituted C2-C8-alkylene or phenylene, X is a chemical bond, oxygen, sulfur, imino, C1-C4-alkylimino, carbonyl or methylene, and Y is oxygen or sulfur, with the proviso that if n is 0, R6 is a fiber-reactive radical, and that the hydroxysulfonyl groups are each ortho to the substituents Q1 and Q2.
