azo dyes, processes for their preparation and use thereof for dyeing and printing hydrophobic fiber materials.

摘要

The dye of the invention can be used for dyeing and printing hydrophobic materials, semisynthetic fiber and, especially, synthetic, especially textile materials. The dye of the invention can be dyed or also embossed fabrics tissue type mixture containing such hydrophobic textile or synthetic, semisynthetic. As semisynthetic textile are considered especially 2 1/2-cellulose acetate and cellulose triacetate. Synthetic hydrophobic textile materials consist primarily of linear aromatic polyesters, for example terephthalic acid and glycols, especially ethylene glycol or condensation products of terephthalic acid and 1, 4- bis- (hydroxymethyl) -cyclohexane; of polycarbonates, eg derivatives, -dimethyl-4, 4-dihydroxy-diphenylmethane and phosgene; of poly (vinyl chloride) and polyamide.
