Abstract

PURPOSE:To improve surface smoothness while reducing both light transmissivity and surface resistance, by providing a metal vapor-deposited film and a lubricant layer on a magnetic coating. CONSTITUTION:On a base film 1 of polyester, etc., a magnetic coating 2 is provided and on it, an about 0.02-0.1mum thickness vapor-deposited film 3 of metal, such as aluminum, zinc, tin, lead, copper, and silver, and a lubricant layer 4 of fluid paraffin, higher fatty acid, fatty acid ester, etc., are further formed.
