| abstract |
Vessel dyes, obtainable by a) halogenation of dibenzanthrone with bromine in the presence of chlorosulfonic acid and a halogenation catalyst, up to a bromine content of 26 to 32% by weight and a chlorine content from 1 to 5% by weight, and b) condensation of the isolated halogenation product with 1-aminoanthraquinone in a molar ratio of 1: 2 to 1: 2.5, in the presence of an inert solvent, the total concentration of halogenated dibenzanthrone and of 1-aminoanthraquinone amounting to at least 200 g / l of solvent. and their use for dyeing or printing textile materials containing cellulose. |
