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, R.sup.1 and R.sup.2 are each independently of the other hydrogen or lower alkyl, X is an alkali-detachable radical, such as fluorine and chlorine, R is hydrogen, lower alkyl or lower alkoxy, and 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.
水溶性蒽醌化合物,其制备以及用作染料的用途。描述了符合以下式(1)的蒽醌化合物,其中A是含磺基的蒽醌基团,R.sup.1和R.sup.2分别独立于另一个是氢或较低烷基,X是可从碱中脱离的基团,如氟和氯,R是氢,较低烷基或较低烷氧基,M是氢或碱金属。这些蒽醌化合物具有纤维反应性质,并用作染料,用于染色和印刷含有羟基和/或羧胺基团的材料,特别是纤维材料,例如纤维素纤维材料、羊毛和合成聚酰胺,呈现出明亮的蓝色调。
