Abstract

PURPOSE:To improve the dispersibility, packing property, etc., of magnetic powder by using a vinyl chloride-vinyl acetate copolymer having epoxy groups and an acrylonitrile-butadiene copolymer in combination as binder components for a magnetic layer. CONSTITUTION:As binder components for a magnetic layer, a vinyl chloride- vinyl acetate copolymer having epoxy groups and an acrylonitrile-butadiene co- polymer are contained. The weight ratio of both the copolymers in use is favorably 8:2-2:8. Further, amines or amided such as ethylene diamine, tetramethylene diamine and dicyandiamide are contained as binder components to improve the wear resistance of the magnetic layer.
