Vat dyes |
| abstract |
Vat dyes obtainable by a) halogenation of dibenzanthrone with bromine in the presence of chlorosulfonic acid and of a halogenation catalyst to a bromine content from 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 from 1:2 to 1:2.5 in the presence of an inert solvent, the concentration of halogenated dibenzanthrone and 1-aminoanthraquinone together being at least 200 g/l of solvent are useful for dyeing or printing cellulose-containing textile material. |
