Abstract: The invention relates to biscationic acid amide and acid imide derivatives with an anion of formula (I), where R9 to R12 are aliphatic, iso- or heterocyclic aromatic residues or aralkyl residues, which may be substituted by alkyl (C1-C4) residues, alkoxy (C1-C4) residues, aryl residues or halogen atoms, or are fluorine atoms, and mixtures of these compounds and mixed crystals with mixed anions and/or cations. The invention also relates to a process for preparing them. The new compounds are excellent colourless charge controllers in toners and developers for electrophotographic recording and as charge-enhancers in powders and paints for surface coating, in particular in triboelectrically or electrokinetically sprayed powder paints.

Abstract: A process for the preparation of highly pure organic pigments which comprises converting organic dyestuffs having various degrees of purity into dyestuff salts capable of being isolated by means of suitable acids which dissolve the impurities contained in the dyestuff, separating them from the acid, recovering the dyestuffs in pure form from the dyestuff salts by the action of water and subjecting the isolated dyestuff in aqueous organic or aqueous-organic medium to a mechanical fine dispersion. By this process the dyestuff formed by the decomposition of the dyestuff sulfate is obtained in highly pure form and can extremely well be brought into a finely dispersed form so that it can be brought into pigment form already by short-time grinding. During the preparation and isolation of the dyestuff sulfate the sulfuric acid is obtained in such a high concentration that it can be regenerated in an economical manner and any ecological charge is avoided.

Abstract: This invention relates to a process for the preparation of a very pure halogenated copper phthalocyanine pigment of the .alpha.-modification which comprises dissolving crude copper phthalocyanine in a 80 to 86% sulfuric acid isolating the copper phthalocyanine sulfate formed, hydrolizing the sulfate and grinding the copper phthalocyanine thus obtained in an aqueousorganic medium.

Abstract: PROCESS FOR PREPARING COPPER PHTHALOCYANINE PIGMENTS OF THE .alpha.-MODIFICATIONs Highly pure .alpha.-coppar phthalocyanine is obtained when a product regenerated from .alpha.-copper phthalocyanine sulfate by hydrolysis with water is aftertreated in an aqueous medium containing a polar organic non-aromatic compound which is water-soluble or liquid. The aftertreated product has an especially high tinctorial strength, is very easily disporsible and has a very pure reddish-blue shade.
