Abstract

4656. Sokal, S., [Kalle & Co., Akt.-Ges.]. Feb. 23. Azo dyes, forming on the material.-Blue shades are obtained by diazotizing on the fibre and developing with a naphthol, the violet dyeings of the secondary disazo dye from 1-naphthylamine-2-sulphonic acid, alpha-naphthylamine, and 2: 5: 7-aminonaphthol sulphonic acid.
