Polyester film with improved surface

Abstract

Abstract PURPOSE:Polyester films whose one side surface is coated with particles of a mixture containing silicone, wax and thickener, thus having smoothness, high slipping and wearing resistance properties. CONSTITUTION:The one surface of a smooth polyester film is coated with a mixture containing silicone, wax and thickener to form a particle layer, whereby the one surface becomes slippery and the other remains smooth. The polyester used is, e.g., polyethlene terephthalate homopolymer or its crystalline copolymer or polyethylene 2,6-naphthalate or its crystalline copolymer. The silicone is preferably crosslinkable silicone as epoxidized dimethylsiloxane. The wax is, e.g., polyethylene or shellac wax.
