Abstract

26,460. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 18. [Addition to 7892/12.] Samples furnished. Chromium sulphonates of azo dyes are obtained by treating chromable azo dyes containing oxy and sulphonic groups, or salts or derivatives thereof, with solutions of chromium salts. Suitable types of dyes are those obtained from diazotized o-aminophenols, o-aminonaphthols, or anthranilic acid, or derivatives thereof, and also those derived from salicylic acid or derivatives thereof. Suitable chromium salts are the fluoride, chloride, acetate, and formate; when salts of mineral acids are used, acid-binding compounds are preferably added, and when the fluoride is used, silicious compounds are added.
