Abstract

535,789. Dyes. DU PONT DE NEMOURS & CO., E.I. Oct. 2Q, 1939, No. 28339. Convention date, Oct. 21, 1938. [Class 2 (iii)] An anthraquinone vat dye dyeing in fast olive shades is made by fusing (6<SP>1</SP>-bromo- Bz] -benzanthronyl)-aminoanthraquinone with. caustic alkali under energetic conditions, whereby the halogen is completely eliminated from the final product. An example is given. Specifications 24601/08, [Class 2], and 348,671 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use as parent materials of 1-(6<SP>1</SP>chloro-Bz1-benzanthronyl) aminoanthraquinone, and also of the 6-bromo or 6-chloro derivatives. This subject-matter does not appear in the Specification as accepted.
