摘要： The invention relates to a coated film and a method for preparing the same, use of the coated film for manufacturing shaped bodies, a method for manufacturing shaped bodies from the coated film, and a shaped body made therefrom. The coated film comprises a plastic film with Shore hardness of not less than 80A and a coating formed by applying an aqueous coating composition to the plastic film, wherein the plastic film is a film of a thermoplastic polyurethane based on polyester polyol, and the aqueous coating composition comprises: a. 45% by weight to 85% by weight of a dispersion of an anionic polyurethane based on polycarbonate polyol; b. 0% by weight to 40% by weight of a dispersion of an anionic polyurethane based on polyether polyol; c. 2% by weight to 18% by weight of a dispersion of anionic silica; d. 0.5% by weight to 10% by weight of a blocked isocyanate; and e. 0.1% by weight to 10% by weight of an additive; the amounts above being relative to the total weight of the composition.
