THREE-LAYER UV PROTECTIVE FILM FOR DECORATIVE LAMINATED SHEETS (HPL) |
摘要 |
The present invention relates to novel films for application to materials as a film providing protection from weathering effects. In particular, the present invention relates to a novel, at least three-layered film composite characterized by particularly good adhesion to the substrate and particularly good optical properties. In this composite, the outermost layer is a layer that contains a fluoropolymer, the middle layer is a PMMA layer that contains at least one UV absorber and/or UV stabilizer, and the innermost layer is a PMMA layer that contains at least one adhesion promoter which improves adhesion to the substrate. |
