摘要： The present invention relates to a dispersion at least comprising particles comprising at least one magnetic iron oxide as component A and a solvent mixture as component B comprising (B1) 5% to 95% by weight of at least one water-miscible organic solvent LM as component B1 and (B2) 5% to 95% by weight of water as component B2, the sum of components B1 and B2 making 100% by weight, and to a method for producing a dispersion of this kind, comprising at least the steps (I) mixing particles comprising at least one magnetic iron oxide with at least one water-miscible organic solvent LM and water, (II) homogenizing the mixture from step (I), where a shearing energy of at least 2 kW/m3 is introduced into the mixture in step (II).
