Magnetic recording media |
| abstract |
MAGNETIC RECORDING MEDIA Abstract This invention relates to coating compositions used for forming a magnetic layer on the surface of substrates to prepare magnetic recording media, e.g., recording tapes, of which the characteristic ingredient is a copolymeric resin. The copolymeric resin is a copolymer obtained by the copolymerization of comonomers in a specified proportion including (1) vinyl chloride, (2) vinyl acetate, and (3) an acrylate or methacrylate moiety having a sulfonic acid group or a metal or amine salt thereof. This copolymeric resin is advantageous in respect of imparting enhanced dispersion and magnetic property characteristics while also having desirable rheological characteristics and thermal stability. |
