Abstract
Procedure for dyeing or printing hydrophobic fiber material, characterized in that the water-insoluble azo dyes of the formula **(See formula)** in which D means the radical of a diazo component; R1 and R2 each signify an alkyl group, optionally substituted; R3 signifies a six-membered heterocyclic radical; and X means a hydrogen atom or an alkyl, aryl, aryloxy, arylthio or alkoxy group, individually or in combination with the desired shade, they are finely ground with the addition of dispersing agents or a combination of wetting and dispersing agents, adding to the dye bath prepared with this product, an imbibing agent for staining at temperatures below 100ºC, or a weak acid such as acetic acid for dyeing under pressure at temperatures above 100ºC; as well as, by means of the thermofixation system, impregnating the fabric, at 60ºC maximum, with an aqueous dispersion of the dye containing 1 to 50% urea and a thickener, preferably sodium alginate, so that the fabric retains dyeing liquid in proportion to the 50 to 100% of its initial weight, the dye being fixed by heating the fabric optionally impregnated in a stream of hot air at temperatures above 100ºC; Also being prepared for printing, in the presence of urea and/or an acid accepting agent together with the usual wetting and thickening auxiliaries.
