Abstract

A stable, liquid, aqueous dyeing composition consisting of (a) 3 to 25 percent by weight of at least one fibre-reactive dyestuff of the formula EQU (HO.sub.3 S).sub.m --F--Z.sub.n in which F represents the radical of a dyestuff chromophore of an anthraquinone-, monoazo-, disazo-, trisazo- or phthalocyanine dyestuff, Z represents a fibre-reactive group, m stands for an integer from 1 to 6 and n stands for an integer from 1 to 3, (b) 3 to 25 percent by weight of at least one disperse dyestuff, (c) 0.5 to 5 percent by weight of a buffer substance, (d) 3 to 40 percent by weight of a dispersing agent, wetting agent, antifreezing agent or preservative or mixtures thereof, and (e) water, and having a pH value between 4 and 7, said dyeing compositions being suitable for the dyeing or printing of blends of fibres containing on the one hand wool, silk, fibres of native or regenerated cellulose, and on the other hand synthetic polyamide, polyacrylonitrile or linear polyesterfibres.
