Abstract
Ternary solid solutions useful as pigments are disclosed. The ternary solid solutions result from incorporating a third component, which is a diketopyrrolopyrrole or quinacridone pigment, into the crystal lattice of the mixed crystal formed from equimolar amounts of two different diketopyrrolopyrrole pigments.
