Abstract

Magnetic recording media which comprise a non-magnetic support and a magnetic layer formed on at least one side thereof, in which the magnetic layer is made of a magnetic composition which comprises magnetic particles dispersed throughout a resin binder consisting essentially of a reaction product of a fluorine resin having at least two hydroxyl groups in one molecule of the resin and a curing polymer material having functional groups capable of reaction with the fluorine resin through the at least two hydroxyl groups.
