Abstract

12,817. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. June 2. [Cognate Application, 27,010/13.] Benzanthrone dyes.-Vat dyes are obtained by treating nitro or amino derivatives of dibenzanthrone or of isodibenzanthrone with aluminium chloride, antimony pentachloride, or phosphorus tri- or penta-chloride; the reaction is preferably carried out in the presence of nitrobenzene. The products dve cotton grev shades. Specifications 16,538/04, 1818/05, 7022/05, and 22,519/05 are referred to. Reference has been directed by the Comptroller to Specification 22,519/05.
