Abstract

1346332 Dioxazine pigments CIBA-GEIGY AG 2 Nov 1971 [16 Nov 1970] 50919/71 Heading C4P [Also in Division C3] The invention comprises dioxazine pigments of the general formula where R 1 and R 2 each denote an aliphatic, cycloaliphatic, aromatic or heterocyclic radical with the proviso that when R 1 is a heterocyclic radical R 2 is an aliphatic or cycloaliphatic radical; Ar denotes an aromatic radical and X denotes H or a substituent which does not impart solubility in water. The pigments may be prepared by cyclization of a diarylaminobenzoquinone of formula where R 3 is alkyl or phenyl, e.g. by heating at 150-210‹ C. in an inert organic solvent, optionally in the presence of an acid halide. The pigments give red shades on natural and synthetic high molecular weight organic materials.
