Abstract

248,766. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning. March 5, 1925, [Convention date]. Addition to 231,529. Mono-azo dyes; lakes.-Azo dyes are produced., either in substance or upon a substratum, by coupling 2: 3-oxynaphthoic arylides with the diazo compounds of 2-amino-4-aroylamino-1- aryloxybenzenes not containing a free hydroxyl group, carboxylic group, or sulphonic group. Claret-red dyestuffs or dyeings are thus obtained which are of more yellowish hue than those described in the parent Specification. According to examples, diazotized 4-benzoylamino-2-amino-1- phenoxybenzene is coupled with 2 : 3-oxynaphthoic-5-chlor-2-toluidide and 2 : 3-oxynaphthoic-anaphthylamide. 4 - Aroylamino-2-amino-1-aryloxybenzenes are obtained by condensing a 1-chlor-2-nitro-4-aroyaminobenzene with an alkali salt of a. phenol and reducing the product.
