摘要 |
<p>A magnetic recording medium comprises a substrate coated with a magnetic layer comprising a binder resin and a metallic magnetic powder supporting silica on the surface which is coated with sequential layers of hydrolyzed silane compound and oleic acid. A magnetic recording medium is produced by sequentially treating a metallic magnetic powder supporting silica on the surface with a solution of a hydrolyzable silane compound and a solution of oleic acid to obtain a magnetic powder having the coated sequential layers and admixing the coated magnetic powder with a binder resin to prepare a magnetic composition and coating the magnetic composition on a substrate to form a magnetic layer.</p> |
