Abstract
An unsupported decorative film of a polymeric composition having controlled permanent tack, the polymeric composition being a blend of 86 to 88% of a polyvinyl acetate-acrylic copolymer of high molecular weight and low residual tack and 12 to 14% of a polyvinyl acetate-maleate copolymer of low molecular weight and high residual tack. Other chemicals may be added to the blend to control color, viscosity and resistance to microorganisms. A casted film of this composition adheres to most surfaces, but may be forcefully removed and relocated. The film is used for decorative art pieces.
