  A magnetic recording medium comprises a nonmagnetic base, on which are formed an electron-cured magnetic resin layer containing dispersed ferromagnetic powder and an electron-cured resin backcoating. The present invention uses an electron-curable vinyl chloride resin having sulfur-containing polar group in combination with an electron-curable urethane resin having a phosphorus-containing polar group. In this way, the dispersion of ferromagnetic powder, surface flatness and electromagnetic conversion characteristics can be improved. Further, an error rate can be reduced in high density digital recording. Further, storage property is excellent.

  This invention relates to coating compositions used for forming a magnetic layer on the surface of substrates to prepare magnetic recording media, e.g., recording tapes, of which the characteristic ingredient is a copolymeric resin. The copolymeric resin is a copolymer obtained by the copolymerization of comonomers in a specified proportion including (1) vinyl chloride, (2) vinyl acetate, and (3) an acrylate or methacrylate moiety having a sulfonic acid group or a metal or amine salt thereof. This copolymeric resin is advantageous in respect of imparting enhanced dispersion and magnetic property characteristics while also having desirable rheological characteristics and thermal stability.
