摘要
The present invention relates to the host-guest solid solutions formed from a mixture of 1,4-diketo-3,6-bis(4-chlorophenyl)pyrrolo[3,4-c]pyrrole (para-dichloro DPP) and 1,4-diketo-3,6-bis(4-methylphenyl)pyrrolo[3,4-c]pyrrole (para-dimethyl DPP). The mixture contains between 30-80 mol percent of para-dimethyl DPP and 70-20 mol percent of para-dichloro DPP. The present invention further relates to the preparation of the solid solutions, and to the use of the solid solutions and binary solid compounds as pigments.
