Abstract

The aminoanthraquinones employed in the printing pastes and printing processes of the parent Specification are replaced by the reaction products of b -aminoanthraquinones and their substitution products with substituted or unsubstituted aromatic sulphochlorides, the preparation and use of the pastes being otherwise carried out as described in the parent Specification and in Specification 349,955. The printing pastes may also contain anthraquinone, hydroxyanthraquinones, aminoanthraquinones, or anthraquinone carboxylic and sulphonic acids or their reduction products containing oxygen, with or without the addition of glycerine or other water-soluble alcohols and hydrotropic agents. Examples are given of the production of printing pastes from 6 : 6<1>-diethoxythioindigo, the dyestuff from 6-methoxy-3-oxythionaphthene and 4-methyl-6-brom-2 : 3- dihydro -3- ketothionaphthene-2-(p-dimethylamino)-anil, the carbazole from dibenzoyl-5:5<1>-diamino-1 : 1<1>-dianthraquinonylamine, and brominated pyranthrone, with the addition of 2-p-toluenesulphaminoanthraquinone or of 2 : 6-di-p-toluenesulphaminoanthraquinone.
