Abstract: Disclosed herein is a method for producing a 1-[4-(biphenyl-4­carbonyl)]phenylaminoanthraquinone colorant composition where the method comprises: reacting 4-halobenzoic acid with about 1 mole to about 4 moles of a halogenating agent per mole of said 4-halobenzoic acid to form a 4-halobenzoyl halide composition; reacting in the presence of a first catalyst composition, said 4­halobenzoyl halide composition with biphenyl, in a solvent, to form a 1-[4-(biphenyl­4-carbonyl)]halobenzene composition; and reacting in the presence of a second catalyst composition and an acid scavenger, said 1-[4-(4-phenylbenzoyl)]halobenzene composition with a 1-aminoanthraquinone, in a reaction medium comprising a dipolar aprotic solvent, to form said 1-[4-(biphenyl-4-carbonyl)]phenylaminoanthraquinone colorant composition.

Abstract: An anthrapyridone composition of the formula: (I) is disclosed, where 'A' and 'B' are independently selected from substituted or unsubstituted cyclic ketone groups having from about 10 to about 20 ring carbon atoms; 'a' is an integer having a value from 0 - 4, R1 - R4 are monovalent substituents; with the proviso that when 'a' is 0, R1 is selected from the group consisting of a hydrogen, an alkyl group, a secondary amino group and an aminosulphonyl group; and R2 - R4 are substituents selected form the group consisting of a hydroxyl group, an aliphatic group, an aromatic group, a heterocylic group, a halogen atom, a cyano group, a carbonyl containing group, an amino group and a sulphonyl-containing group. The anthrapyridones are useful as thermally stable colorants for producing colored polymer resins and articles that require high temperature polymer processing conditions.
