Abstract

PURPOSE:To obtain a magnetic recording medium which has a magnetic layer having high cross-linking density, large modulus of elasticity, and excellent wear resistance, by utilizing cross-linking reaction by irradiating an acrrylic oligomer with an electron beam. CONSTITUTION:With a 100pts.wt. resin mixture consisting of 30-80pts.wt. vinyl chloride resin and 70-20pts.wt. rubber resin, a 10-200pts.wt. acrylic oligomer having >=3 functions, such as the reaction product of trimethylolpropane and 2-hydroxyethyl(meth)acrylate, the reaction product of pentaerythritol and 2- hydroxyethyl(meth)acrylate, and the reaction product of dipentaerythritol and 2-hydroxyethy(meth)acrylate, is mixed to obtain a binder. Magnetic paint which uses the said binder is applied to a base and irradiated with an electron beam, thus obtaining a magnetic recording medium of cross-linking structure by the cross-linking reaction of the acrylic oligomer.
