Title (EN) DECORATIVE FILM
(FR) FILM DECORATIF
Abstract:
(EN) A decorative film having an excellent decorative effect, excellent three-dimensional curvature emulating properties, three-dimensional curvature formability, long-term weather resistance and stain resistance. The decorative film comprises one or more transparent layers and a decorative metal layer. The transparent layer has an adhered side for being adhered to a substrate. The transparent layer comprises a copolymer of a tetrafluoroethylene, a hexafluoropropylene and a vinylidene fluoride. The decorative metal layer is on the adhered side of the transparent layer. A substrate can be bonded to the metal layer of the decorative film. The substrate can be a complex three-dimensional shaped substrate. The substrate can also be an injection molded substrate. An adhesive can be disposed on the metal layer of the decorative film, and the adhesive layer can be disposed between the metal layer and the substrate.
(FR) L'invention concerne un film décoratif doté d'un excellent effet décoratif, d'excellentes propriétés d'émulation de courbe tridimensionnelle, d'une formabilité de courbe tridimensionnelle, d'une résistance aux intempéries à long terme et d'une résistance aux taches. Le film décoratif comprend une ou plusieurs couches transparentes et une couche métallique décorative. La couche transparente comporte un côté adhésif lui permettant d'adhérer à un substrat. La couche transparente comprend un copolymère de tétrafluoroéthylène, un hexafluoropropylène et un fluorure de vinylidène. La couche métallique décorative se trouve sur le côté adhésif de la couche transparente. On peut lier un substrat à la couche métallique du film décoratif. Le substrat peut consister en un substrat complexe tridimensionnel. Le substrat peut également être un substrat moulé par injection. On peut disposer un adhésif sur la couche métallique du film décoratif et la couche adhésive peut être disposée entre la couche métallique et le substrat.
