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.

A quaternary solid solution consisting of from 40 to 96 weight-percent of a quinacridonequinone component, from 1 to 45 weight-percent of a quinacridone component, from 2 to 30 weight-percent of a pyrrolo[3,4-c]pyrrole component and from 1 to 20 weight-percent of an acridone 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;
- wherein the quinacridonequinone component is a compound of the formula ##STR24## in which R is hydrogen, halogen, or C.sub.1 -C.sub.4 alkyl, and x and y are independently 1 or 2;
- the quinacridone component is a compound of the formula ##STR25## wherein each R" is independently hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or trifluoromethyl;
- the pyrrolo[3,4-c]pyrrole component is a compound of the formula ##STR26## in which each Ar is independently an aryl substituent of the formula ##STR27## wherein R.sub.1 and R.sub.2 are independently of each other hydrogen, halogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy, --SR.sub.3, --N(C.sub.1 -C.sub.5 alkyl).sub.2, --CF.sub.3, --CN or a substituent of the formula ##STR28## wherein R.sub.3 is C.sub.1 -C.sub.5 alkyl and R.sub.4 and R.sub.5 are independently of each other hydrogen, halogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy, --SR.sub.3 or --CN, wherein R.sub.3 is C.sub.1 -C.sub.5 alkyl;
- and wherein the acridone component is a compound of the formula ##STR29## or a compound of the formula ##STR30## wherein A is O or NH and R' is hydrogen, halogen or C.sub.1 -C.sub.4 alkyl.
