Zusammenfassung:PURPOSE:To improve a recording characteristic, etc. by coating a coating liquid consisting of a multifunctional acrylate compd. and an org. solvent within a specific b.p. range on a non-magnetic base having surface roughness of a specific value or above and drying the same then irradiating radiations thereto to provide an intermediate film and forming a magnetic layer thereon. CONSTITUTION:A coating liquid contg., for example, diethylene glycol diacrylate, trimethylol propane acrylate or the like contg. >=2 acryloyl or methacryloyl groups, an org. solvent having 50-120 deg.C b.p. under atm. pressure, for example, a solvent such as n-hexane, methyl ethyl ketone, ethyl acetate ester, etc. and if necessary contg. a thermoplastic resin such as a vinyl chloride/vinyl acetate copolymer or the like and having preferably
