Anthracene, dyes derived from.-A vat dye is obtained by treating aminonaphthanthraquinone with acid condensing-agents, such as antimony pentachloride. Other vat dyes are obtained by halogenizing this dye, for instance by brominating with bromine alone or in presence of nitrobenzene or sulphuric acid, or by chlorinating ; halogen carriers may be employed. The products dye cotton grey and bluish-grey shades.
