| titleOfInvention | Magnetic recording medium |
| abstract | An object of the present invention is to provide a magnetic recording medium that is excellent in dispersibility, coating film smoothness, electromagnetic conversion characteristics, durability, and long-term storage, has little MR head corrosion, and has a small environmental impact during incineration. Magnetic recording having a magnetic layer in which a lower layer containing inorganic powder and / or magnetic powder and a binder is provided on a nonmagnetic support, and at least one ferromagnetic fine powder and a binder are dispersed thereon. In the medium, the binder in the lower layer is 45 to 80% by mass of a radically polymerizable monomer having nitrogen as a raw material with respect to the total amount of monomers, and (meth) acrylate having an alkyl (meth) acrylate and / or a benzene ring. It is obtained by reacting an organic diisocyanate with an acrylic copolymer obtained by copolymerizing monomers and having a hydrophilic polar group in the molecule, and a polyol compound having a cyclic structure and a long-chain alkyl chain. And a polyurethane resin having a hydrophilic polar group in combination. |
