Abstract

PURPOSE:To obtain a stable-quality magnetic recording medium, by combining the radiation sensitive modified resin and the radiation sensitive elastomer. CONSTITUTION:The radiation sensitive modified resin which shows >=1.0X10<3> dynes/cm<2> dynamic elasticity modulus within 20-60 deg.C temperature range in 100Hz before modification due to sensitivity to radiation and has the unsaturated double bond and the soft resin which sowns <=1.0X10<9> dynes/cm<2> dynamic elasticity modulus within 20-60 deg.C temperature range in 100Hz or the radiation sensitive soft resin such as the prepolymer, oligomer, and telomer of said soft resin which has the unsaturated double bond are mixed in 8:2-2:8 to obtain a binder. Ferromagnetic particles are dispersed into this binder, and said resins are cross-linked and polymerized by radiation to obtain a magnetic recording medium.
