Abstract

10,420. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. May 4. Dyes, artificial.-Azo dye-stuffs dyeing wool in an acid bath bluish-red are prepared by combining the diazo compound of 4-chlor-2-aminopheuol-6- sulphonic acid with 1-naphthol-4-sulphonic acid or with 1-naphthol-5-sulphonic acid. On chroming, the tint produced changes to navy-blue in the case of the dye-stuff from 1-naphthol-5-sulphonic acid, and to a tint somewhat redder than this, in the case of the dye-stuff from its isomer.
