Abstract
The present invention provides a formable hard coating composition, comprising a binder, comprising at least one acrylate oligomer and at least one monofunctional acrylate monomer and a crosslinking agent, comprising at least one multifunctional acrylate or methacrylate monomer. Furthermore, the present invention provides a coated film comprising a coextruded PC/PMMA film and a coating obtained by coating with the hard coating composition, wherein the coating has a dry film thickness according to ASTM B499 in the range of from ≥1 to ≤6 μm and preferably a crosslink density in the range of from ≥2·10to ≤13·10. The coated films exhibit a combination of good formability and pencil hardness, solvent and chemical resistance which makes it particular useful for applications such as in-mold decoration processes.
