Abstract
PURPOSE: To enhance both the magnetic and orientation properties by mixing the alkylether-type surface active agent functioning as the antistatic agent plus RCOOH.M-type surface active agent into the binder containing the polyurethane resin.
CONSTITUTION: The magnetic recording medium is made by applying the magnetic coating material featuring the following composition to the substrate of polyester or the like. The binder to be mixed with the magnetic material uses the vinyl chloride-vinyl acetate polymer platicized with the polyurethane resin of not more than 40wt% to the whole binder quantity. Then the alkylether-type surface active agent functioning as the antistatic agent and the RCOOH.M-type (R: alkyl or alkylphenyl group; M: amine) surface active agent of not more than 50% of total amount of the surface active agent are mixed together to obtain the magnetic coating material. As a result, the half-life of the magnetic recording medium can be reduced, at the same time increasing the magnetic orientation property.
