Abstract:
The present invention provides magnetic recording media comprising a magnetizable layer and optionally a backside coating provided on a nonmagnetizable substrate. At least one of the magnetizable layer and the optional backside coating comprises a polymeric binder, wherein the polymeric binder is obtained from reactants comprising a free radical generator and a radiation curable polymer. The radiation curable polymer comprises a plurality of radiation curable, .alpha.-methylstyrene moieties of the formula ##STR1##
