Magnetic recording medium
 A magnetic recording medium is disclosed. The medium is comprised of a non-magnetic flexible support having a subbing layer coated thereon with a magnetic layer coated on the subbing layer. The subbing layer is comprised of a copolymer of a diolefin and a vinyl monomer. The subbing layer provides excellent adhesiveness between the support and the magnetic layer and can be produced without the use of organic solvents. Accordingly, the subbing layer can be economically produced without environmental pollution.
