Isomericmixture of reactive dyes and their use for the dyeing or printing of textile fibre materials.

Abstract

The present invention relates to the field ofisomeric mixture of reactive dyes that are suitable for the dyeing or printing of nitrogen-containing or hydroxy-groupcontaining fibre materials and yield on such materials dyeings or prints having a good build-up behaviour, a high fixation rate, good washing off properties of the unfixed dyes and good all-round fastness properties, as well as a good stability to various dyeing parameters such as a good bath stability. Furthermore, the present invention relates to a processfor dyeing or printing of nitrogen-containing or hydroxy-group-containing fibre materials, wherein the isomeric mixture of reactive dyes according to the invention isused.
