HPL - UV THREE-LAYER UV PROTECTIVE FILM FOR DECORATIVE LAMINATED SHEETS HPL

摘要

The present invention is directed to novel films for application to materials as films providing protection against weathering effects. In particular, the present invention relates to novel film composites having three or more layers, especially characterized by good adhesion to substrates and particularly good optical properties. In this composite, the outermost layer is a layer containing a fluoropolymer, the intermediate layer is a PMMA layer containing one or more UV absorbers and / or UV stabilizers, and the innermost layer is one that improves adhesion to the substrate Is a PMMA layer containing the adhesion promoter described above.
