Abstract

294,291. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). April 26, 1927. Monoazo dyes yielding violet shades are produced in substance or on the fibre by coupling the diazotized aminonaphthol ethers with arylides of 2 : 3-oxynaphthoic acid. In an example diazotized 7-methoxy-1-aminonaphthalene is coupled with the #-naphthylamide; the product gives a reddish-violet shade fast to chlorine, boiling, and light. Specifications 6379/12, and 17279/13, [Class 15 (ii), Dyeing, Processes &c. for], are referred to.
