<p>PURPOSE:To establish the magnetic recording media excellent in the running performance and frequency characteristics, by using the binder formed in addition of the vinylchloride vinylacetate copolymer including vinylalcohol to the resin component of the vinylchloride-vinylacetate copolymer and the polyester resin. CONSTITUTION:Vinylchloride-vinylacetate copolymer including 10wt% or more vinylalcohol is taken as the binder through preparation of it to the resin component consisting of vinylchloride-vinylacetate copolymer and polyester resin with less than 50wt% (to total binder resin component), and magnetic paint is formed with scattering of magnetic powder to it, and the magnetic recording media is manufactured with the said magnetic paint.</p> |
