Abstract

1,172,662. Blue anthraquinone dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 March, 1968 [22 March, 1967], No. 13632/68. Heading C4P. [Also in Division C3] Blue anthraquinone dyes of general formula (I) in which A is a cycloaliphatic radical containing an endomethylene group and the anthraquinone ring may bear substituents in the 5, 6, 7 and/or 8 positions are prepared by elimination of the 2-sulphuric acid group by reduction of the corresponding 2-sulphonic acid compounds. The dyes give blue shades on polyamide textile materials.
