Abstract:
Dye mixtures comprising at least one dye of the formula (1) ##STR1## together with at least one dye of the formula (2) or (3) ##STR2## in which the substituents are as defined in claim 1 are direct dyes for cellulosic fibre materials in particular. They are stable at high temperatures and are particularly suitable for the one-bath, single-stage dyeing of polyester/cotton blends with a disperse dye for the polyester fibres under the dyeing conditions for polyester fibres.
Abstract:
The invention relates to a process for dyeing or printing hydroxyl group containing fiber materials, which comprises using at least one yellow or orange dyeing dye of formula ##STR1## wherein the substituents are as defined in claim 1, together with at least one blue dyeing dye and/or at least one red dyeing dye. Level dyeings and prints with good allround fastness properties are obtained by the process of the invention.
