ABSTRACT:
Binary and ternary pigmentary solid solutions are disclosed. The binary solid solutions are binary solid compounds consisting of 35-45 weight-percent unsubstituted DPP and 55-65 weight-percent dichloro DPP. The ternary solid solutions are guest-host solid solutions wherein the binary solid compound is the host and up to 30 weight-percent of a disubstituted quinacridone pigment is the guest. The binary and ternary solid solutions are useful as pigments for coloring high-molecular-weight organic materials; especially as replacements for perylene pigments in automotive finishes.
