Abstract

Navy dye mixtures essentially contain dyes of the formula I ##STR1## where X is hydrogen, chlorine or bromine, the radicals R.sup.1 independently of one another are each methyl or ethyl and R is a radical of the formula ##STR2## where A is ##STR3## B is unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl, phenyl-C.sub.1 -C.sub.4 -alkyl, phenoxy-C.sub.2 - or -C.sub.3 -alkyl or cyclohexyl and R.sup.2 is C.sub.1 -C.sub.4 -alkyl, the mixtures containing from 20 to 80 parts of dyes in which R is NH-A-COOB and from 80 to 20 parts of dyes in which R is ##STR4## The novel mixtures are very useful for dyeing synthetic polyesters, and give dyeings which have, in particular, very good heatfastness.
