ABSTRACT:
This invention provides certain blue substituted 1,4-bis(2,6-dialkylanilino) anthraquinones in combination with selected red anthraquinone and anthrapyridone (3H-dibenz[f,ij] isoquinoline-2,7-dione) compounds which provide a toner system useful in imparting a desirable neutral to slightly blue hue to polyesters having a yellow appearance. The thermally stable colored compounds can have polyester reactive groups and are preferably incorporated into the polyester polymer structure during polymerization.
