Abstract: Quinacridones having selectively adjusted triboelectric effects, which quinacridones contain about 0.05% to 100 percent by weight of triboelectrically active compounds of the general formula I (I), in which Q is a quinacridone radical which is unsubstituted or substituted by halogen atoms, alkyl, alkoxy, H2N-CO-, alkyl-NH-CO- or (alkyl)2N-CO groups, A is a direct bond or -O-, -S-, -NR1-, -CO-, -SO2-, -CR2R3- or arylene and Y is an -NR4R5 group or a five-, six- or seven-membered heterocycle which contains one to three heteroatoms from the series comprising nitrogen and/or oxygen and/or sulfur and which can be substituted by alkyl, alkoxy, hydroxyphenyl, halogen, -CN, -COOH, -CO-NRR', -SO2-NRR', hydroxyalkyl or alkylaminoalkyl, in which R and R' together with the nitrogen atom can be a heterocycle, R and R' are hydrogen atoms or alkyl and R1 to R5, independently of one another, are each hydrogen and/or alkyl or alkenyl of 1 to 22 carbon atoms and n is a number from 1 to 4, and their use for the preparation of toners or developers which are used for electrophotographic copying or reproduction of originals and for printing electronically, optically or magnetically stored information or are used in color proofing.

Abstract: Process for specifically influencing the triboelectric effect of azo pigments in electrophotographic toners or developers or in powders for surface coating by adding to the azo pigments at the coupling reaction stage, at the laking stage or in the course of finishing at least one saltlike, cationic compound whose positively charged center is a nitrogen, phosphorus, arsenic or antimony atom or the group , and use of such azo pigments for producing toners or developers used for the electrophotographic copying or manifolding of originals or for printing electronically, optically or magnetically stored data or in colorproofing or use of such azo pigments for producing powders or powder coatings used for the surface coating of articles made of metal, wood, plastics, glass, ceramics, concrete, textile material, paper or rubber.

Abstract: Described are electret fibres with improved charge stability (stabilisation) which consist of a material which predominantly contains a fibre-forming addition or condensation polymer and 0.01 to 30% by weight (preferably 0.01 to 10, in particular 0.1 to 5, % by weight), based on the weight of the material, of organic or organometallic charge control agents, as is contained in toners for electrophotographic processes, and a process for the production thereof. Also described are textile materials containing these electret fibres.

Abstract: HOE 91/F 412 of the disclosure: Diallylammonium compounds, processes for their preparation and their use Ionic monomeric diallylammonium compounds having a targeted combination of diallylammonium cations with selected anions have particularly high and constant charge control properties and very good heat stabilities and dispersibilities. The compounds according to the invention are outstandingly suitable for use as colorless charge control agents in toners and developers for electrophotographic recording processes and for use as charge-improving agents in powders and paints for surface coating, in particular in triboelectrically or electrokinetically sprayed powder paints.
