Abstract

Azo dyes are made in substance on a substratum or on the fibre by coupling the diazo compound of an o-nitroaminodiarylether with an arylide of 2 : 3-oxynaphthoic acid or a derivative thereof further substituted in the naphthalene nucleus. In examples (1) the dyestuff 3-nitro-4-aminodiphenylether --> the b - naphthalide is prepared in substance, (2) cotton is impregnated with the p-chloranilide and developed with diazotized 4<1>-chloro - 3 - nitro - 4 - aminodiphenylether. Other diazo components specified are the 4<1>-bromo-or iodo- or 2<1> : 4<1>-dibromo-3-nitro-4-amino-diphenylether and other coupling components the anilide, o- and m-chloranilide, a -naphthalide, o-, m-, and p-toluidide, 4- and 5-chlor-2-toluidide, o- and p-anisidide, o- and p-phenetidide, 4-chlor-2-anisidide, di-anisidide, and 3 : 4- or 2 : 5-dichloranilide. The dyestuffs may be produced on wool, silk, and artificial silk.
