Abstract

298,697. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 18, 1927. Azo dyes, insoluble in water, are produced in substance, on a substratum, or on the fibre by coupling diazotized unsulphonated aminofluorenones with suitable components such as naphthols, 2 : 3-oxynaphthoic arylides, oxynaphthocarbazoles, or diacetoacetyl or like derivatives of aromatic diamines. In examples, monoaminofiuorenone is coupled with 2 : 3-oxynaphthoic anilide or dianisidide or with #-naphthol; 2:7 diaminofluorenone with 2 : :3-oxynaphthoic anilide, 7-oxynaphthocarbazole or diacetoacetyl tolidine.
