ABSTRACT:
The invention relates to dye mixtures comprising at least one dye of formula (1) ##STR1## wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy and R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl, together with at least one dye of formula (2) ##STR2## wherein R.sub.3 is hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, R.sub.4 is hydrogen or C.sub.1 -C.sub.4 alkyl and R.sub.5 is C.sub.2 -C.sub.6 alkyl uninterrupted or interrupted by oxygen, with the proviso that R.sub.1 is not methyl when R.sub.2, R.sub.3 and R.sub.4 are hydrogen and R.sub.5 is ethyl.
The dye mixtures are suitable for dyeing or printing natural or synthetic polyamide fibre materials, especially in combination with other dyes and especially from short liquors. The dye mixture is distinguished by generally good properties, especially good uptake and good solubility.
