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.
