Abstract

Azo dyes; azo dyes, forming on the material.-Azo dyes are made in substance or on a substratum by coupling a diazo compound of an aromatic or heterocyclic non-sulphonated amine or derivative thereof or an aromatic aminoazo compound or diamine with an arylide of a hydroxyphenanthrene-o-carboxylic acid. In an example, cotton padded with 2-hydroxyphenanthrene-3-carboxylic acid-o-toluidide is developed with diazotized 2 : 5-dichloraniline (yellowish red). Other arylides specified are 3-hydroxyphenanthrene-2-carboxylic acid-o-toluidide and p-anisidide and other diazo components: o- and p-nitraniline, 5-nitro-o-anisidine, 5-chloro-2-toluidine, m-aminoazotoluene, 2-amino-5-benzoylaminohydroquinone diethylether, dianisidine, 1-, 2- or 3-aminocarbazole, 9-ethyl-3-aminocarbazole, 2-aminodiphenyleneoxide, p-nitro-o-toluidine, p-chlor-o-nitraniline, m-nitro-p-toluidine, 4-nitro-2 : 5-dimethoxy-41-aminoazobenzene. Arylides of hydroxyphenanthrene carboxylic acids and made from the corresponding acid and amine by boiling in an inert organic solvent in presence of a condensing agent, e.g. phosphorus oxychloride.
