Isomeric mixture of reactive dyes and its use for dyeing or printing textile fiber materials.

Abstract

The present invention relates to the field of isomeric mixtures of reactive dyes that are suitable for dyeing or printing nitrogen-containing or hydroxy group-containing fiber materials and produce dyes or prints on said materials that have good build-up behavior, a high fixation rate, good wash-off properties of unfixed dyes, and good overall fastness properties. as well as good stability to various dyeing parameters, such as good bath stability. Furthermore, the present invention relates to a process for dyeing or printing nitrogen-containing or hydroxyl-containing fiber materials, in which the isomeric mixture of reactive dyes according to the invention is used.
