Abstract

PURPOSE:To reduce the traveling friction, by coating silicone on the magnetic surface of a magnetic tape. CONSTITUTION:A magnetic layer is formed on the base surface of a polyethylene terephtalate film, etc. At the same time, a silicone layer is formed on the other surface of the film by coating and drying a composition consisting of the silicone, a solvent, a curing agent and a catalyst thereafter heat-curing.
