Abstract

PURPOSE: To obtain a magnetic recording medium which excels in the electromagnetic converting performance, the surface smoothness, etc., by using a binder obtained the 3-component group resin.
CONSTITUTION: The resin consisting of 15W50% polyester resin, 10W50% epoxy resin and 20W60% vinyl chloride-vinyl acetate copolymer resin is used for a binder. Then magnetic powder, a dispersant, a lubricant and other necessary materials are mixed and dispersed with addition of a curing agent to obtain a magnetic coating material. This coating material is applied on a supporter to form a magnetic recording medium.
