A new group of azoic pigments has been synthesized by coupling 5-chloro-oxine with diazotized aromatic amines. According to this reaction, aniline, o-, m-, and p-chloroanilidies, 0-, Ct-, and p-bromoanilines, o-, m-, and p-nitroanilineq, p-aminophenol, 2,4-dichloroaniline, o-anisidine, p-toluidine, 5-nitro, o-toluidine, p-aminoazobenzene hydrochloride, p-aminodiphenyl, p-aminoacetanilide alpha-and beta -naphthylamines, etc., have yielded such azoic pigments as are mostly deep red in colour. 5-Chloro-oxine can be prepared most economically from the waste of D.D.T. manufacture available in the country (Pakistan J. scient. industr. Res., 1966,9: 78).
