A highly water-soluble composition for the dyeing or printing of native or synthetic polyamide fibres consisting essentially of (a) 10 to 99 parts by weight of at least one dyestuff ##STR1## IN WHICH X represents hydroxy, methyl, ethyl, methoxy or ethoxy, and Y represents hydrogen or methyl, and (b) 0.5 to 90 parts by weight of an auxiliary agent of the group consisting of a polyglycol of an average molecular weight from 3000 to 20 000, a polyglycolether (containing 15 to 30 ether groups) of a fatty alcohol of 8 to 20 carbon atoms, an alkali metal salt of a dialkylnaphthalene sulfonic acid (alkyl C.sub.1 -C.sub.6), a methyltauride of a saturated or unsatruated fatty acid of 8 to 20 carbon atoms, and an isethionate of a saturated or unsaturated fatty acid of 8 to 20 cabron atoms, and mixtures thereof, said composition being also suitable for the dyeing or printing of the said polyamide fibres in deep shades.
