摘要：
A magnetic recording medium comprising a transparent plastic film substrate, a primer coating layer formed on the substrate and a magnetic layer for magnetic recording formed on the primer coating layer, wherein said primer coating layer is formed by dispersing carbon black in a radiation curable coating material composed essentially of at least one oligomer or polymer containing at least one radiation curable unsaturated double bond per molecule and curing the resulting dispersion by radiation.
