Abstract
1,177,892. Anthraquinone dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 20 March, 1968 [21 March, 1967], No. 13382/68. Heading C4P. Blue anthraquinone dyes of Formula I in which A and A<SP>1</SP> denote identical or different cycloaliphatic radicals containing endomethylene groups and the anthraquinone nucleus may bear substituents in the 5, 6, 7 and/or 8 positions are prepared by reacting one or more compounds of Formula II in which X is an amino or hydroxyl group and which may bear substituents in the 5, 6, 7 and/or 8 positions and which compounds are partly or wholly in the form of their leuco compounds with one or more amines of formula A-NH 2 in which A is as above. The leuco compounds may also be formed in situ during the reaction by the action of a reducing agent, e.g. hydrochloric acid and zinc dust.
