Beschreibung
Zusammenfassung:	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.
