Abstract
The invention comprises compounds of the formula <FORM:1114956/C4-C5/1> and salts thereof, where one of X and X1 is a sulphonic acid group and the other is a sulphonamide group and the methyl groups are meta or para to the amino groups. The compounds are prepared by reacting 1-4-dichloro anthraquinone-6-carboxylic acid with meta- or paratoluidine and reacting the ditoluidino anthraquinone produced first with chlorosulphonic acid and then with ammonia.
