A novel resinous binder composition is disclosed for a magnetic recording tape. Magnetic particles are dispersed within a resinous matrix having both a hard and soft component. The hard component is fabricated by exposing a resin capable of being cured by electron beam irradiation to set the radiation forming a semi-interpenetrating network with 'soft' material.

Radiation cured binders internetworked with soft materials

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.
