Abstract

1387899 Monoazo pigments CIBA-GEIGY AG 19 Dec 1972 [20 Dec 1971] 58660/72 Heading C4P Novel pigments of the formula (wherein R 1 and R 4 are optionally substituted phenylene radicals, R 2 is an optionally further substituted naphthalene radical in which the azo, hydroxyl and -CO- groups are respectively in the 1-, 2- and 3-positions; R 3 is an optionally substituted aryl or aralkyl radical; and R 5 is an optionally substituted phenyl or naphthyl radical) are prepared (i) by condensing a compound of the formula wherein Hal is a halogen atom, e.g. Cl (in turn prepared by halogenation of the corresponding free acid, this being prepared by coupling a diazotized amine H 2 N-R 1 -CONHR 3 with a 2,3-hydroxynaphthoic acid) with a compound of the formula or (ii) by coupling a diazo or diazoamino compound of an amine of the formula with an appropriately substituted 2,3-hydroxynaphthoic acid amide. The novel pigments are used for pigmenting high molecular organic material (an example describes the preparation of a red PVC film).
