    • An anthrapyridone composition of the formula: 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 heterocyclic 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.
    • 公开了下式的蒽吡啶酮组合物,其中“A”和“B”独立地选自具有约10至约20个环碳原子的取代或未取代的环酮基; “a”是0-4的整数,R1-R4是一价取代基; 条件是当“a”为0时,R 1选自氢,烷基,仲氨基和氨基磺酰基; 和R 2 -R 4是选自羟基,脂族基团,芳族基团,杂环基,卤素原子,氰基,含羰基的基团,氨基和含磺酰基的基团的取代基 。 蒽吡啶酮可用作用于生产着色聚合物树脂的热稳定着色剂和需要高温聚合物加工条件的制品。
