Abstract

1,172,154. Monoazo dyes. SANDOZ Ltd. 1 March, 1967 [11 March, 1966], No. 9627/67. Heading C4P. Monoazo disperse dyes of Formula I in which R 1 is chlorine or bromine, R 2 is an alkyl radical or etherified hydroxy or mercapto group, R 3 is hydrogen or alkyl, alkoxy or acylamino, R 4 is hydrogen or an alkyl group, R 5 is an alkylene radical and R 6 is an acyloxy or carboxylic acid ester group and each of the radicals R 2 -R 6 may bear one or more further non-watersolubilizing substituents (in groups other than carboxylic acid or sulphinic acid groups) are prepared by diazotizing an amine of Formula II and coupling with a compound of Formula III The dyes give yellow-brown shades on linear aromatic polyesters, polyamides and cellulose di- and tri-acetates, conventional dyeing. methods being employed.
