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, R
1
-R
4
are monovalent substituents; with the proviso that when “a” is 0, R
1
is selected from the group consisting of a hydrogen, an alkyl group, a secondary amino group and an aminosulphonyl group; and R
2
-R
4
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.
公开了一种具有以下结构的蒽吡啶酮组合物:其中“A”和“B”分别选自具有约10至约20个环碳原子的取代或未取代的环酮基团;“a”是取值范围为0-4的整数,R1-R4是一价取代基;但当“a”为0时,R1选自氢、烷基、二级氨基和氨基磺酰基组成的基团;R2-R4是选自羟基、脂肪基、芳香基、杂环基、卤素原子、氰基、含羰基的基团、氨基和磺酰基的取代基。这些蒽吡啶酮可用作热稳定的着色剂,用于生产需要高温聚合物加工条件的着色聚合物树脂和制品。
