Abstract

New sulphur dyes are obtained by sulphurizing arylamino naphthols which may contain further substituents such as halogen atoms or sulphonic groups. According to examples the following compounds are sulphurized with sodium polysulphide in presence of glycol monomethyl ether as solvent; 6-anilino-2-naphthol, 6 - p - chloranilino - 2 - naphthol, 6 - p - toluidino - 2 - naphthol, 7 - anilino - 2 - naphthol, 7 - 2<1> - naphthylamino - 2 - naphthol, phenyl - g - acid, and phenyl - J - acid. The arylamino naphthols are obtained by treating the corresponding 2 : 6 or 2 : 7 dihydroxynaphthalene with the amine in presence of aqueous sodium bisulphite.
