    Abstract: A blue colouring agent with positive regulating properties for electrophotographic recording processes is essentially composed of a compound having the formula (I) and characterized, in the X-ray diffraction pattern, by a strong band at 2delta° (CuKalpha) 18.47, by three medium bands at 2delta (CuKalpha) 18.47, by three medium bands at 2delta (CuKalpha) 5.97, 12.01, 13.90 and by three weak wide bands at 2delta° (CuKalpha) 20.0, 21.7, 22.5, 24.8, 28.2, 30.7, 32.2. The colouring agent is used for producing toners or developers useful for electric photocopying or reproducing documents and for printing electrically, optically or magnetically recorded information or for colour-proofing.

    Abstract: - 1 - HOE 90/F 277 of the disclosure: Polymer ammonium borates and processes for their preparation Polymer ammonium borates having a molecular weight from about 5000 to about 500,000 and obtained by homopolymerization of monomers, such as, for example, diallyldialkylammonium chloride, and by copolymerization of mixtures of two monomers, such as, for example, diallyldimethylammonium chloride and diallylmethyloctylammonium chloride, having molar monomer ratios of about 0.5:0.5 to about 0.95:0.05 in the copolymer, followed, if desired, by anion exchange, and mixtures of these compounds. Polymer ammonium borates according to the invention are suitable as colorless charge-control agents in toners and developers for electrophotographic recording processes and as charge-improving agents in powders and coatings for surface coating.
