Abstract

PURPOSE:To suppress tape squeaking while reducing a secular change of a magnetic paint during preparation, by using a specific setting component and a surface active agent. CONSTITUTION:To resin components, such as a vinyl chloride-vinyl acetate copolymer and polyurethane resin, isoholodiisocyanate as a setting component and saturated fatty-acid sorbitan ester, such as tristearic acid sorbitan ester, as a surface active agent are added. The obtained magnetic paint is applied on a base to obtain a magnetic recording medium.
