A dye mixture, comprising at least one blue dyeing dye of the formula (1), wherein Qrepresents a bivalent radical of formula (4), (4) or (4), wherein Xdenotes chlorine or fluorine, Ris hydrogen or C-Calkyl, Ris hydrogen, C-Calkyl, C-Calkoxy or sulfo, Yis vinyl or a radical &#x2014;CH&#x2014;CH&#x2014;U and U is a leaving group removable under alkaline conditions, Ris hydrogen or C-Calkyl that is unsubstituted or substituted by hydroxy, sulfo, sulfato, cyano, carboxy, C-Calkoxy or phenyl, r and s are each independently of the other the number 0 or 1, and t is the number 0, 1 or 2, and the sum of r, s and t is 2 or 3 and at least one yellow or red dyeing reactive dye is suitable especially for the dichromatic or trichromatic dyeing or printing of natural or synthetic polyamide fibre materials and yield dyeings or prints having good reproducibility and good all-round fastness properties. 

Mixtures of reactive dyes and their use in a method of di- or trichromatic dyeing or printing

A method of dyeing or printing textile fiber materials, which comprises bringing the fiber material into contact with (a) at least one reactive dye containing at least one anionic group, (b) at least one compound which reduces the ionic character of the anionic group, and (c) at least one nucleophilic compound, yields dyeings or prints having deep hues and very good fastness properties.

Method of dyeing or printing textile fibre materials using reactive dyes

Method for the trichromatic dyeing or printing of synthetic polyamide fiber material, wherein at least one red reactive dye of formulais used together with at least one of the yellow or orange reactive dyes of formulaeand at least one blue reactive dye of formulain which formulaethe variables are as defined in claim 1,which method is distinguished by a uniform color build-up and a very good combinability.
