    摘要： Magnetic recording media are produced by preparing a dispersion of anisotropic magnetic materials in solution in an organic binder using dispersants and further conventional additives, applying the dispersion in the form of a layer onto a nonmagnetic substrate and solidifying the applied magnetic layer, by a process in which a cylindrical grinding chamber is used which is provided with an anchor stirrer or helical stirrer and contains grinding media whose specific gravity is lower than that of the magnetic material.

    摘要： A process for the preparation of a magnetic recording medium by dispersing pulverulent magnetic material in a binder mixture which is dissolved in an organic solvent and essentially consists of an elastomeric polyurethane and a high molecular weight hydroxyl-containing polymer, with addition of dispersing assistants and conventional additives, applying a layer of the dispersion, to which a diisocyanate and/or polyisocyanate has first been added, to a base material and the solidifying the layer and crosslinking the binder matrix, wherein the diisocyanate and/or polyisocyanate is added to the dispersion and, before applying the dispersion to the base, from 15 to 55% of the NCO groups present react with the hydroxyl-containing polymer of the binder mixture.

    摘要： Magnetic recording media which have a thin backing coating and consist of a non-magnetic flexible base and a magnetic layer which is applied to one side of the base and comprises magnetic material finely dispersed in an organic binder are produced by applying a dispersion of finely divided non-magnetizable conductive and non-conductive solids and conventional additives in a solution of a polymeric binder in an organic solvent to that side of the base which is opposite the magnetic layer by means of a knife-coater, and then drying the layer, a high molecular weight organic compound which acts as a thickener being added to the backing coating dispersion.
