Abstract

PURPOSE: To increase the heat-resistance and anti-wear performance, by cross-linking the magnetic layer taking specific resin as the binder, through the processing of cross-linking agent.
CONSTITUTION: The emulsion of the (co)polymer including the functional base without the activity H, e.g., epoxy base and aziridine base, such as ethylacrylate- methylmethacrylate-glycidylmethacrylate copolymer, and the magnetic powder are mixed into water emulsion system magnetic paint, which is coated on the base and dried to form the magnetic layer. The cross-linking agent which reacts with the said functional base in cross-link, such as a compound having carboxyl, OH, amino, preferably the solution of the resin such as methylacrylate-acryl acid copolymer, is coated and dried on the magnetic layer so that the amount of cross-linking agent can be 30 to 250mg/m2, then it is heated, cross linking the (co)polymer in the magnetic layer.
