Abstract
Dye mixtures comprising a reactive dye having at least one structural unit of formula (1) together with a reactive dye of formula (2), wherein (Q1)0-3 and (Q2)0-3 each independently of the other denote from 0 to 3 identical or different substituents selected from the group halogen, C1-C4alkyl, C1-C4alkoxy, carboxy and sulfo, Z1 and Z2 are each independently of the other a fibre-reactive radical, at least one fibre-reactive radical being contained in the dye of formula (1) and the dye of formula (2) containing at least one fibre-reactive radical Z1 or Z2, are suitable for dyeing cellulosic or nitrogen-containing fibre materials.
