Abstract
The present invention relates to novel solid solutions which comprise a quinacridonequinone component, a pyrrolo[3,4-c]pyrrole component and a third component which is a 2-anilinoacridone, a 5,6,7,8-tetrahydro-2-anilinoacridone, 2-phenoxyacridone, a 5,6,7,8-tetrahydro-2-phenoxyacridone or a mixture thereof. The solid solutions are three component solid solutions which consist of the components identified above or are four component solid solutions which additionally contain a quinacridone component. Pigment compositions containing the disclosed solid solutions and a method of pigmenting high molecular weight organic material with the solid solutions are also disclosed.
