Zusammenfassung:1. Process for the preparation of 1-amino-4-bromoanthraquinone-2-sulphonic acid and its salts by reacting elemental bromine with an aqueous solution of 1-aminoanthraquinone-1-sulphonic acid at customary temperatures and pH values and in the presence of oxidising agents, characterised in that bromic acid or its salts are used as the oxidising agent.
