Abstract

Layer-type magnetic recording media are produced by applying a dispersion of a magnetically anisotropic material in a binder solution onto a flexible plastic base provided with an adhesion-promoting layer and then solidifying the magnetic layer, by a method in which the adhesion-promoting layer consists of a radiation-curable aqueous dispersion of a polymer.
