Pigment compositions, and the preparation method and use of the same

摘要

Compositions comprising water-based coating materials and a ternary 1,4-diketo-3,6-diphenylpyrrolo[3,4-c]pyrrole composition comprising compounds of formulae (I), (II) and (III), wherein X₁ and X₂ are each independently of the other hydrogen or chlorine, with the proviso that X₁ and X₂ are not simultaneously hydrogen, and R₁ and R2 ? are each independently of the other hydrogen, C₁-C₆alkyl, chlorine, bromine, C₁-C₆trifluoroalkyl, C₁-C₆alkoxy or a phenyl radical unsubstituted or substituted by C₁-C₆alkyl, chlorine, bromine or by C₁-C₆alkoxy, with the proviso that compounds of formulae (I), (II) and (III) are different, and also a process for the preparation thereof, and novel ternary 1,4-diketo-3,6-diphenyl-pyrrolo[3,4-c]pyrrole compositions, and the use thereof in the pigmenting of high or low molecular weight material
