The invention relates to novel, water-soluble anthraquinone dyes which, in the form of the free acid, have the formula I <IMAGE> (I) in which X is halogen, R1 is an unbranched or branched alkyl radical having 4 to 8 carbon atoms, R2 and R3 independently of one another are an unbranched or branched alkyl radical having 1 to 4 carbon atoms, R4 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, R5 is hydrogen or an unbranched or branched alkyl radical having 1 to 4 carbon atoms and R6 and R7 independently of one another are hydrogen, an unbranched or branched alkyl radical having 1-4 carbon atoms, a -SO3H group, halogen or a radical of the formula -CH2-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 R6 or R7 is a -SO3H group.
