Abstract

311,400. I. G. Farbenindustrie Akt.- Ges. May 11, 1928. [Convention date]. Azo dyes; lakes.-Azo dyes are made either in substance or on a substratum by coupling 2: 3. oxynaphthoic acid - 2<1> - methyl-5<1>-isopropyl-1<1>- anilide with a diazo compound of the aminoazo compound obtained from diazotized o-phenetidine and a-naphthylamine or from diazotized pnitraniline and aminohydroquinone dimethylether. Specifications 203,032 214,516 and 214,649, [Class 15 (ii), Dyeing, Processes &c. for ], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the dyestuffs derived from dianisidine, 4-aminodiphenylamine and its derivatives and the aminoazo compounds obtained from any diazo compound and a-naphthylamine or an aminohydroquinonedialkylether. This subject-matter does not appear in the Specification as accepted. 2: 3-Oxynaphthoic acid-2<1>-methyl-5<1>-isopropyl- 1<1>-anilide is made from 2: 3-oxynaphthoyl chloride and 2-methyl-5-isopropyl-1-aminobenzene.
