ABSTRACT:
A novel resinous binder composition is disclosed for a magnetic recording tape or like media. Magnetic particles are dispersed within a resinous matrix having both a "hard" and a "soft" component. The "hard" component is fabricated by exposing a resin capable of being cured by electron beam irradiation.
The magnetic recording media coating is very apt for use with harsh pigment like CrO.sub.2 particles and is adapted for frequent contact with a head, being adapted to exhibit good durability, abrasivity, etc. by virtue of using a lubricant system including a fluoro-silicone oil and a compatible fatty-acid-ester like butoxy ethyl stearate.
