Abstract

PURPOSE: To increase not only the durability but the solvent-resistance performance of a magnetic recording medium, by using the polyvinyl butyral, copolymerized polyester containing the sulfonic acid metal base and trifunctional low molecular weight isocyanate compound in combination as the magnetic layer binder.
CONSTITUTION: The magnetic recording medium contains the following materials for the magnetic layer binder components: the polyvinyl butyral; the copolymerized polyester containing the sulfonic acid metal base; and the trifunctional low molecular weight isocyanate compound each. With use of such binder, both the dispersing and filling properties of the magnetic powder can be enhanced. At the same time, not only the durability but the solvent-resistance performance can be increased for the magnetic recording medium.
