Abstract

The process of the parent Specification, according to which the azo dyes obtained by coupling an o-diazonaphthol with 1-oxynaphthalene-8-sulphonamide are converted into soluble chromium compounds, is extended to the production of metal compounds of the azo dyes made by coupling any o-oxydiazo compound with any oxynaphthalene-sulphonamide, whether a mono- or a poly-sulphonamide, wther than the 1-oxynaphthalene-8-sulphonamide. Chromium and copper compounds are specified. The products dye wool in very varied shades from an acid bath. Azo dyes from the following components are specified: as diazo components:-1-amino-2-naphthol-4-sulphonic acid, 2-aminophenol-4-sulphonic acid, 4-chlor- or 4 : 6-dichlor-2-aminophenol, 4-nitro-6-chlor- or 6-nitro-4-chlor-2-aminophenol, 2-amino-1-oxynaphthalene-8-sulphonamide-4-sulphonic acid; as coupling components:-1-oxynaphthalene-4- or -5-sulphonamide, 2-oxynaphthalene-6-sulphonamide, 1-oxynaphthalene-8-sulphonamide- 3- or -4-sulphonicacid, 1-oxynaphthalene-3 : 8- or -4 : 8-disulphonamide. In examples is described the production of chromium compounds by boiling the dyestuffs with chromium formate, or with chromium fluoride and glass powder, and of a copper compound by boiling with copper sulphate. Oxynaphthalene-sulphonamides may be obtained from the corresponding naphtholsulphonic acids by acidylating the -OH group, converting the sulpho-group into the sulphochloride and then into the sulphonamide group, and finally eliminating the acidyl group. The 1 : 4-, 1 : 5-, and 2 : 6-naphtholsulphonamides, the 1 : 8-naphtholsulphonamide- 3 or -4-sulphonacid, and the 1 : 3 : 8- and 1 : 4 : 8-naphtholdisulphonamides are mentioned. The oxynaphthalene sulphonamide sulphonic acids are made by treating the corresponding naphthsultone sulphonic acids with ammonia; 1 ; 8-naphthol-sulphonamide-3- and -4-sulphonic acids are specified.
