Abstract
PURPOSE: To obtain a magnetic recording medium for a magnetic recording tape, etc., which has dispersibility and surface property improved, by forming a magnetic layer by dispersing magnetic powder in a binder of -SO3Na group containing resin.
CONSTITUTION: In a binder obtained by introducing an -SO3Na group as a side chain for polyester resin (further containing thermoplastic polyurethane and nitrocellulose at need), fixed ferromagnetic powder is dispersed. This magnetic coating is applied on a polyester film, etc., and then dried to form a magnetic recording tape. This magnetic coating is excellent in surface property and superior in surface workability, so that the magnetic tape can be obtained which has improved surface reflectivity, residual magnetic-flux density, S/N, etc.
