Abstract
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.
