A process for the simultaneous tanning and dyeing of collagen containing fibrous material, wherein the said material is treated with a liquor containing at least one reactive dyestuff selected from the group of formula (1) and (2)

Process for the simultaneous tanning and dyeing of collagen containing fibrous material

The present invention relates to azo dyes of formula wherein

Disperse azo dyes, a process for the preparation thereof and the use thereof

Fibre reactive formazan dyes, their preparation and their use

The present invention relates to disperse azo dyes based on diazo components having at least one fluorine-containing substituent and an 2,6-diaminosubstituted pyridine coupling component, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fiber materials, more especially textile materials.

Disperse azo dyes

Provided are processes for dyeing or printing fibre materials using reactive dye mixtures. The reactive dyes mixtures have been found to be suitable for dyeing or printing hydroxyl-group containing fibre materials or nitrogen-containing fibre materials. The dyeings or prints obtained according to such processes exhibit good all around fastness properties.

Mixtures of reactive dyes and their use

Reactive dye mixtures comprising at least one red dyeing dye and at least one blue, yellow, orange or brown dyeing dye and their use in methods for the dichromatic or trichromatic dyeing or printing of cellulosic fiber materials are described. The reactive dye mixtures yield dyeings or prints having good reproducibility and good all-round fastness properties.
