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.
Claims20
A flexible plastic coated film comprising a base film and a polymeric coating thereon wherein:
- A. the base film comprises a polyvinyl chloride resin, from about 10 to 60 parts by weight for each 100 parts of resin of a polymeric plasticizer resulting from the condensation of a polyhydric alcohol and a dibasic organic acid and about 10 to 50 parts based on 100 parts by weight of the resin of an alloying polymer selected from the group consisting of acrylonitrilebutadiene copolymer rubber and ethylene-n-butyl acryiate-carbon monoxide polymer;
- and
- B. the coating comprises a member selected from the group consisting of polymethyl methacrylate and polymethyl methacrylate mixed with a flexibilizing polymer for the polymethyl methacrylate, and mixtures thereof;
- C. the quantity of polymethyl methacrylate is at least 50% by weight of the polymeric material in the coating;
- and
- D. the plastic coated film has a thickness of about 0.003 to 0.02 inches.
A flexible polyvinyl chloride resin film of a base film coated with a polymeric stain resistant coating wherein:
- A. the base film comprises for each 100 parts of polyvinyl chloride resin from 10 to 60 parts of a polymeric plasticizer which is the condensation product of a polyhydric alcohol and a dibasic organic acid, 10 to 50 parts of an alloying polymer selected from the group consisting of (a) an acrylonitrilebutadiene copolymer rubber containing about 15% to 50% by weight thereof of acrylonitrile;
- and (b) ethylene-n-butyl acrylate-carbon monoxide polymer, the parts of ingredients in said base film being by weight;
- and
- B. said film is coated with a polymeric coating containing at least 50% by weight of polymethyl methacrylate.
A flexible stain resistant and cleanable coated film comprising a base film and a polymer coating thereon wherein:
- A. the base film comprised 100 parts of polyvinyl chloride resin, 10 to 60 parts of polymeric plasticizer wherein the polymeric plasticizer is the condensation product of a polyhydric alcohol and a dibasic organic acid, and an alloying polymer selected from the group consisting of 10 to 50 parts of acrylonitrile-butadiene copolymer rubber and ethylene-n-butyl acrylate -carbon monoxide polymer, said parts being by weight of the base film, and
- B. the coating comprises at least 50% of polymethyl methacrylate based on the weight of polymer in the coating.
