Abstract: A method of manufacturing a vinyl chloride-coated steel sheet involving the steps of coating electron ray curable adhesives on the surface of a thin metal sheet, such as a zinc plated steel sheet or cold rolled steel sheet, laminating a vinyl chloride film of decorative and corrosion resistant protecting properties to the coated surface and irradiating the upper surface of the coated sheet with electron rays thereby bonding the film with the metal sheet, wherein the vinyl chloride film is formed by applying a calendering or extruding process to a blend including a vinyl chloride resin obtained by suspension polymerization and from 20 to 40 parts by weight of a plasticizer, dialkyl tin mercaptide type stabilizer, an acryl oligomer type lubricant and optionally, pigments and other ingredients.
