Abstract
507,169. Dyes. I. G. FARBENINDUSTRIE AKT.-GES. Dec. 10, 1937, No. 34233. Convention date, Jan. 13. [Class 2 (iii)] Ortho-oxyazo dyes are .made by coupling a propyl or-butyl ester of 2-oxynaphthalene-6- carboxylic acid (obtainable by esterifying the 2-oxynaphthalene-6-carboxylic, acid described in Specification 257,815, [Class 2 (iii)], with a propyl or butyl alcohol) with a diazotized 2- aminobenzene-1-carboxylic acid containing a sulphonic acid group. They dye wool red by the chroming process. In examples 2-amine-5- sulphobenzoic acid is coupled with the n-propyl and n-butyl esters, and 2-amino-4-sulphobenzoic acid is coupled with the isobutyl ester.
