## Abstract

A stain resistant, easily cleanable and flexible plastic coated film comprising a base film and a coating thereon wherein the base film comprises a polyvinyl chloride resin, a polymeric plasticizer, and a member selected from the group consisting of acrylonitrile-butadiene copolymer rubber and ethylene-n-butyl acrylate-carbon monoxide polymer and the coating comprises polymethyl methacrylate alone or together with a flexibilizing polymer such as vinyl chloride-vinyl acetate copolymer and/or a flexibilizing copolymer of methyl methacrylate. The coated film gives superior oil and stain resistance as compared to the base film or coating alone.
