Abstract: Dye mixtures which comprise a reactive dye of the formula ##STR1## together with at least one reactive dye of the formulae ##STR2## in which D, D', R.sub.1, R.sub.2, R.sub.3, R.sub.3 ' and B are as defined in claim 1, are particularly suitable for dyeing or printing cellulosic fibre materials or naturally occurring or synthetic polyamide fibre materials with a high tinctoffal yield, and produce dyeings and prints having good fastness properties.
