Abstract
25,903. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 20. Monoazo dyes are obtained by combining the diazo compounds of 4-chlor-2-aminophenol or its substitution derivatives with 1-acidylamino-8- naphthol sulphonic acids. Products are specified from: -4-chlor-2-aminophenol and 1-acetylamino-8-naphthol-5-sulphonic acid. I-acetylamino-8-naphthol-3:6-disulphonic acid, or 2<1> : 4<1>-dichlorbenzoyl-1-amino-8-naphthol-4:6-disulphonic acid, 4-chlor-2-aminophenol-6-sulphonic acid and 1-acetylamino-8-naphthol-5-sulphonic acid; the nitro-4-chlor-2-aminophenols and 4:6- dichlor-2-aminophenol are also specified as components. The products dye wool shades, which, on chroming, become violet-blue to blue.
