Abstract: HOE 90/F 278K Polymeric ammonium compounds as charge control agents Use of polymeric ammonium salts which have a molecular weight of about 5000 to about 500,000, and are obtained by homopolymerization of monomers, such as, for example, diallyldialkylammonium chloride, or by copolymerization of mixtures of two monomers, such as, for example, diethyldimethylammonium chloride and diallylmethyloctylammonium chloride, with molar monomer ratios of about 0.5:0.5 to about 0.95:0.05 in the copolymer, and if appropriate subsequent anion exchange, individually or in combination as charge control agents in electrophotographic toners and developers which are employed for copying or duplicating masters and for printing electronically, magnetically or optically stored information or in colorproofing, and as charge control agents in powders and powder coatings.

Abstract: Use of inclusion compounds of cyclic polysaccharides as charge control agents Inclusion compounds consisting of a host compound, which is a cyclically linked polysaccharide having 3 to 100 monomeric saccharide units and forming a cavity in its molecular framework, and of one or more chemical compounds which are included in this cavity as guest compound(s), are used as charge control agents and charging improvers in electrophotographic toners and developers, in triboelectrically or electrokinetically sprayable powders and powder coatings and in electret materials.

Date Jul. 11, 1991.The invention relates to biscationic acid amide and acid imide derivatives with an anion of formula (BR9R10R11R12)-, where R9 to R12 are aliphatic, iso- or heterocyclic aromatic residues or aralkyl residues, which may be substituted by C1-C4-alkyl residues, C1-C4-alkoxy residues, aryl residues or halogen atoms (e.g. 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 colorless 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.
