摘要： A magnetic recording material and a process for producing it are disclosed. The material is excellent in abrasion resistance and has good electric characteristics. The material is obtained by coating on a support a subbing layer having a compound which contains a compound having an unsaturated bond polymerizable upon irradiation with electron beams. Upon the subbing layer is coated a ferromagnetic layer which contains a compound having an unsaturated bond polymerizable upon irradiation with electron beams, an organic solvent capable of dissolving the compound, and a ferromagnetic fine powder. The material is then subjected to an electron-beam irradiating processing to result in the hardening of the subbing and ferromagnetic layers through polymerization.
