ABSTRACT:
The invention relates to novel, water-soluble anthraquinone dyes which, in the form of the free acid, have the formula I ##STR1## in which X is halogen, R.sub.1 is an unbranched or branched alkyl radical having 4 to 8 carbon atoms, R.sub.2 and R.sub.3 independently of one another are an unbranched or branched alkyl radical having 1 to 4 carbon atoms, R.sub.4 is hydrogen, an unbranched or branched alkyl radical having 1 to 4 carbon atoms, a free or acylated amino group or a fibre-reactive radical bonded via an amino group, R.sub.5 is hydrogen or an unbranched or branched alkyl radical having 1 to 4 carbon atoms and R.sub.6 and R.sub.7 independently of one another are hydrogen, an unbranched or branched alkyl radical having 1-4 carbon atoms, a --SO.sub.3 H group, halogen or a radical of the formula --CH.sub.2 --NH--CO--Y, in which Y is an alkyl or alkenyl radical having 1 to 4 carbon atoms which is unsubstituted or substituted by one or two halogen atoms, or is a substituted or unsubstituted phenyl radical, with the proviso that at least one of the radicals R.sub.6 or R.sub.7 is a --SO.sub.3 H group.
