A colored polyester copolymer comprising the reaction product of at least one linear thermoplastic polyester precursor and at least ten parts per million by weight of a residue of at least one 1,4-bis (2,6-dialkylanilino)-9,10-anthraquinone colorant. A composition may be formed comprising the copolymer in admixture with at least one thermoplastic polymer. The copolymer may be formed by reacting at least one thermoplastic polyester precursor with a 1,4-bis (2,6-dialkylanilino)-9,10-anthraquinone colorant which has a polyester reactive group.
一种彩色聚酯共聚物,包括至少一种线性热塑性聚酯前体和至少10 ppm重量的至少一种1,4-双(2,6-二烷基苯胺基)-9,10-蒽醌着色剂残留物的反应产物。可以形成一种混合了至少一种热塑性聚合物的共聚物组合物。该共聚物可以通过将至少一种热塑性聚酯前体与具有聚酯反应基的1,4-双(2,6-二烷基苯胺基)-9,10-蒽醌着色剂反应而形成。
