Abstract

PURPOSE: To form a magnetic layer of excellent coating durability by using a compound substance, obtained by mixing an acrylic compound with an unsaturated bond and thermoplastic resin at a specific ratio, as a binder for the magnetic layer and then by setting it through irradiation with radiant rays.
CONSTITUTION: As a binder, a compound substance that contains an acrylic compound with not less than two unsaturated bonds in one molecule and thermoplastic resin such as polyurethane in 80:20W20:80 proportion is used. Magnetic coating obtained by mixing this binder with proper magnetic powder, etc., is applied on the base of a film, etc., and, after dried, set by being irradiated with radiant rays. This method improves the filling rate to increase Rs and also sets excellent by the magnetic layer through low radiation irradiation to improve the wear resistance of the coating.
