摘要： A mixed crystal of two or more different benzimidazolonedioxazine compounds of the formula (1) 1 where X and Xnull are identical or different and are hydrogen or halogen, R1, R1null, R2 and R2null are identical or different and are hydrogen, C1-C18 alkyl, trifluoromethyl, C1-C18 alkylcarbonyl, C5-C6 cycloalkyl or phenyl which may be unsubstituted or substituted by one or more halogen atoms, nitro groups, trifluoromethyl, C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylcarbonyl and/or C1-C18 alkoxycarbonyl groups. The mixed crystals are of low solubility and feature good fastness properties and red to blue colorations. The mixed crystals are suitable for pigmenting paints, plastics, printing inks, aqueous or solvent-based pigment preparations, electrophotographic toners and developers, powder coating materials, inks, preferably inkjet inks, color filters, and for coloring seed and cosmetics.
