Abstract

Azo dyes; azo dyes, forming on the material.-An azo dyestuff yielding turkey-red tints fast to light and boiling lye is made by combining 2 : 3-hydroxynaphthoyl - 11 - amino - 31 - chloro - 21 : 41-di-methoxybenzene with diazotized 1-amino-3-methyl-4 : 6-dichlorobenzene either in substance or on a substratum. Examples are given of the ice-colour process, producing the dyestuff in substance and of a printing process. Specifications 6379/12, [Class 2 (iii), Dyes &c.], 17279/13, and 287,479, [both in Class 15 (ii), Dyeing, Processes &c. for], are referred to. 2 : 3-Hydroxynaphthoyl-11-amino-31-chloro-21 : 41-dimethoxybenzene is made from 2 : 3-oxynaphthoic acid and the corresponding amine. 1-Amino-3-chloro-2 : 4-dimethoxybenzene is made by treating 1-nitro-2 : 3-4-trichlorobenzene with sodium methylate (2 mols.) and reducing the 1-nitro-3-chloro-2 : 4-dimethoxybenzene thus obtained.
