Dye mixtures and their use

Abstract

Dye mixtures which contain a dye of the formula ##STR1## together with a dye of the formula ##STR2## in which M.sup.+ in the dyes of the formulae (1) and (2) are ammonium cations ##STR3## which are identical to or different from one another, of an amine of the formula ##STR4## where R.sub.1 and R.sub.2 independently of one another are hydrogen, C.sub.1 --C.sub.6 alkyl or C.sub.2 --C.sub.6 alkyl substituted by hydroxyl or amino and, if appropriate, interrupted by an oxygen atom, and R.sub.3 is C.sub.2 --C.sub.6 alkyl substituted by hydroxyl or amino and, if appropriate, interrupted by an oxygen atom, afford dyeings having good fastnesses on nitrogen-containing or hydroxyl group-containing fibre materials.
