ABSTRACT:
Described are dye mixtures comprising dyes containing a coupling component comprising a 1-(chlorotriazinyl)amino-3,6-disulfo-8-naphthol radical, the dye or dyes of the one group of dyes containing an optionally loweralkyl-, loweralkoxy-, halogen, sulfo- and/or carboxy-substituted phenylamino or naphthylamino radical attached to the chlorotriazine radical and possessing a diazo component comprising an optionally loweralkyl-, loweralkoxy-, sulfo- and/or carboxy-substituted phenyl radical which is substituted by a fiber-reactive group of the vinyl sulfone series, and the dye or dyes of the other group of dyes containing attached to the chlorotriazine radical a phenylamino radical whose phenyl is substituted by a fiber-reactive group of the vinyl sulfone series and may be substituted by lower alkyl, lower alkoxy, sulfo and/or carboxy, and possessing a diazo component comprising a radical of benzene or naphthalene which may in each case be optionally substituted by lower alkyl, lower alkoxy, halogen, sulfo and/Qr carboxy. The dye mixtures are useful for preparing a dyeings and prints on hydroxy and/or carboxamido-containing fiber material, for example cotton and viscose fibers, and also wool and synthetic polyamide fiber materials and afford strong fast dyeings having a red hue.
