Abstract
317,419. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 15, 1928. Azo dyes lakes. - Azo dyestuffs giving clear red shades fast to light are produced in substance, on a substratum, or on the fibre by coupling with arylides of 2 : 3-oxynaphthoic acid diazotized dichloro-o-toluidines having one chlorine atom in p-position to the methyl group. In examples cotton is dyed clear bluish red, fast to light, (1) by impregnation with the 2<1> : 5<1>-dimethoxyanilide of 2: 3 oxynaphthoic acid and development with diazotized 4: 5-dichloro-2- toluidine, (2) by impregnation with the 4<1>- anisidide and development as in (1), (3) by impregnation with the alpha-naphthylamide and developmem. with diazotized 4: 6-dichloro-2-toluidine. Specifications 6379/12; and 17279/13, [Class 15 (ii), Dyeing, Processes &c. for], are referred to.
