Abstract

PURPOSE:To offer a magnetic recordng medium free from deterioration in coating film strength and an increase in the amount of magnetic paint sticking to a head while a secular change during magnetic paint preparation is reduced, by using a specific setting component and a surface active agent. CONSTITUTION:To a resin component consisting of a vinyl chloride-vinyl acetate copolymer, polyurethane resin, etc., isoholodiisocyanate as a setting component and a compound, such as C11H23-COOH(C4H3)3, shown by general formula R-COOH.M (M is amine and R is alkyl group) as a surface active agent are added respectively to prepare magnetic paint, which is applied on a base to obtain a magnetic recording medium.
