ABSTRACT:
A process for producing a magnetic recording medium by applying onto a base a magnetic coating composition comprising ferromagnetic particles dispersed in a solution comprising a compound polymerizable by electron beams and a low boiling solvent is disclosed. The ferromagnetic particles in the applied magnetic coating are oriented while it is still wet, and thereafter the oriented web is irradiated with electron beams within 5 seconds after orientation to retain the ferromagnetic particles orientation and the web is dried by evaporating the solvent.
