ABSTRACT:
In a magnetic recording medium comprising a plastic base film and a magnetic layer, the base film is plasma treated at frequencies in the range of 10 kHz to 200 kHz in an inorganic gas containing at least 5% of oxygen. The magnetic layer is formed on the plasma treated base film by applying a magnetic composition of ferromagnetic fine particles dispersed in a plasticized binder compound comprising a radiation-sensitive modified resin in admixture with a radiation-sensitive modified flexible resin or prepolymer, oligomer or telomer thereof, and exposing the composition to radiation for crosslinking and polymerization.
