Wherein A, B, a and K are as defined in the claims.

Description

METAL-FREE REACTIVE DYES, PROCESS FOR THE PRODUCTION THEREOF AND THEIR USE BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to the technical field of reactive dyes for the dyeing and printing of hydroxyl-, amino- and / or carboxamido-containing materials.

Metal free reactive dyes are known in the prior art and can be used as colorants in different applications (see, for example, US 20030172476).

However, in connection with the dyeing and printing of hydroxyl-, amino- and / or carboxamido-containing materials, known dyes which are metal free have a number of technical drawbacks, such as unsatisfactory light fastness, There is a limit to achieving darker hues such as sex levels of dark violet, dark brown, navy and black tones.

Surprisingly, the dyes of formula (I) described below exhibit very favorable properties compared to known dyes known. This includes a high build-up of a darker hue with high fastness properties such as light fastness to the above-mentioned materials and formulations containing them, cleaning and contact fastness. Most importantly, the dyes of formula (I) are metal-free and thus provide dyeings with excellent ecological performance and very good leveling properties.

The present invention represents dyes of the formula (I) and mixtures thereof, wherein the invention represents all types of tautomers and geometric isomers of the dyes of formula (I)
