<p>PURPOSE:To obtain the magnetic recording media excellent in the running stability, bonding force, light glitter, and electromagnetic conversion performance, by using magnetic paint taking the resin component consisting of three specific components as binder. CONSTITUTION:Polyurethane resin having OH radial (e.g., Niporan 3032, made by Nippon Polyurethane K.K.) at the end, (a), 30-70wt%, epoxyresin (e.g., Epicoat 1007, made by Shell K.K.) (b), 10-50wt%, and vinyl chloride-vinylidene chloride resin (e.g., Denka Vinyl #1000W, made by Denki Kagaku K.K.) (c) 10-50wt%, (constituent hatched in Fig.) are taken as binder and magnetic paint is formed by preparing magnetic powder to it, and magnetic recording media is obtained by coating this magnetic paint to the base film such as polyester film.</p> |
