Abstract
PURPOSE:To improve luster, etc., by using a vinyl chloride-vinyl acetate-vinyl alcohol copolymer, having high vinyl acetate content and low vinyl alcohol content, as the binding component of the magnetic layer of a magnetic recording medium. CONSTITUTION:A vinyl chloride-vinyl acetate-vinyl alcohol copolymer is prepared which contains >=5% vinyl acetate and <=8% vinyl alcohol. This copolymer is used as the binding component of the magnetic layer of a magnetic recording medium and 20-90wt% resin in terms of group is contained in the binding component to obtain the titled magnetic recording medium. As the binding components other than this copolymer, a rubber binder of acrylonitrile-butadiene rubber, etc., urethane resin of an urethane elastomer, urethane prepolymer, etc., or polyisocyanate is used favorably.
