ABSTRACT:
The invention relates to dye compositions for obtaining level dyeings on carboxamido-containing and hydroxyl-containing fiber materials, which dyeings have comparably good light and wetlightfastness properties, the dye compositions containing dioxazine dyes (I) and disazo dyes (II) (one or more than one from IIa to IIf) in a weight ratio of 90:10 to 10:90, preferably 60:40 to 10:90, in particular 40:60 to 15:85.
