Azo dyestuffs of the formula ##SPC1##Wherein A and B are different radicals of an aromatic coupling component are described. The new dyestuffs are outstandingly suitable for dyeing and printing natural or synthetic fibre materials containing hydroxyl groups and nitrogen like wool, wool-cotton union, silk, high molecular polyamide as well as paper pulp and paper materials and leather to give dyeings havings good fastness properties.
摘要:
Azo dyestuffs of the formula ##STR1## wherein A, R.sub.1, m and n have the meaning given in the description. The dyestuffs are suitable for dyeing cellulose-containing materials, especially cotton, which may be natural or regenerated, as well as union fabrics containing cotton, and paper. The dyestuffs in general give red to violet, as well as reddish brown, color shades.The dyestuffs are distinguished by good light-fastness, substantivity and wet-fastness. Their great suitability for high temperature dyeing processes and for subsequent creaseproof finishing deserves particular mention.

The invention relates to the preparation of storage-stable, concentrated solutions of urea compounds of the formulaF.sub.1 --HN--CO--NH--F.sub.2wherein F.sub.1 and F.sub.2 denote radicals of dyestuffs or dyestuff intermediates containing acid groups by reacting 2 equivalents of amines of the formulaF.sub.1,2 --NH.sub.2with one equivalent of a compound of the formulaCl--CO--Xwherein X is chlorine or an aryloxy radical in the presence of alkaline earth metal ions in the pH range of 4.0 to 8.0, separating off the sparingly soluble alkaline earth metal salt of the resulting urea compounds, adding -- for example -- a salt of lithium of which the anion forms a salt, which is sparingly soluble in the reaction medium, with the alkaline earth metal cation of the urea compound to the suspension of these urea compounds and separating off the alkaline earth metal salt which has precipitated.
