Abstract

Water-soluble anthraquinone compounds, preparation thereof, and use thereof as dyes. There are described anthraquinone compounds conforming to the formula (1) ##STR1## where A is the radical of a sulfo-containing anthraquinone radical, PA1 R.sup.1 and R.sup.2 are each independently of the other hydrogen or lower alkyl, PA1 X is an alkali-detachable radical, such as fluorine and chlorine, PA1 R is hydrogen, lower alkyl or lower alkoxy, and PA1 M is hydrogen or an alkali metal. The anthraquinone compounds have fiber-reactive properties and are used as dyes for dyeing and printing hydroxy- and/or carboxamido-containing material, in particular fiber material, for example cellulose fiber materials, wool and synthetic polyamide, in brilliant blue shades.
