Zusammenfassung:	The present invention relates to novel films for application on materials as protective film in respect of weathering effects. In particular, the present invention relates to a novel film composite which has at least three layers and which features particularly good adhesion on the substrate and particularly good optical properties. The outermost layer here is a layer comprising a fluoropolymer, the middle layer is a PMMA layer comprising at least one UV absorber and/or UV stabilizer, and the innermost layer is a PMMA layer comprising at least one adhesion promoter which improves adhesion on the substrate.
