摘要 |
Disclosed herein is a magnetic recording medium, (1) in which a magnetic layer is formed by coating a magnetic paint containing a magnetic powder and a binder as its main components on a non-magnetic base material; (2) which is featured by containing as said binder a polymer having an alkenyl phenol as one of the components of the polymer; and (3) which has markedly improved effects in the dispersibility of the magnetic powder in said medium and in the abrasion resistance and flexibility of the magnetic layer.
