Fluororesin film and fluororesin-laminated acrylic resin film
View Patent ↗An object of the present invention is to provide a novel monolayer and multilayer film that can be employed also for use in interior and exterior members of vehicles, and that have excellent transparency, surface hardness, chemical resistance, and stain resistance such as lactic acid resistance and sunscreen resistance. The present invention is directed to a fluororesin film formed with (C) a fluororesin comprising (B) a fluorinated (meth)acrylic resin that contains a fluorine-containing alkyl(meth)acrylate polymer component; and a fluororesin-laminated acrylic resin film, wherein the fluororesin film layer is laminated on at least one face of a film layer comprising (A) an acrylic resin.
1. A fluororesin film formed with
(C) a fluororesin comprising
(B) a fluorinated (meth)acrylic resin that contains a fluorine-containing alkyl (meth)acrylate polymer component, wherein said fluorine atom is bonded directly to said alkyl group,
wherein the fluororesin (C) comprises polyvinylidene fluoride in a content of 0.1 to 10 parts by weight relative to 100 parts by weight of the fluorinated (meth)acrylic resin (B);
wherein the fluororesin film has a thickness of 30-300 μm and
wherein the fluorine-containing alkyl (meth)acrylate polymer is a copolymer of 90 to 99.9% by weight of a fluorine-containing alkyl (meth)acrylate and 0.1 to 10% by weight of another copolymerizable monomer.
2. The fluororesin film according to claim 1 , wherein the content of the fluorine-containing alkyl (meth)acrylate polymer component is not less than 80% by weight relative to 100% by weight of the fluorinated (meth)acrylic resin (B).
3. A molded article produced by laminating the fluororesin film according to claim 1 .
4. The fluororesin film according to claim 1 , wherein the fluororesin film is produced by melt extrusion.
5. The fluororesin film according to claim 1 , wherein the fluororesin film is a monolayer.
6. The fluororesin film according to claim 1 , wherein the copolymerizable monomer is at least one selected from the group consisting of methacrylic acid esters, acrylic acid esters, halogenated vinyls, vinyl cyanide, vinyl esters, aromatic vinyl derivatives, halogenated vinylidenes, acrylic acid and salts thereof, acrylic acid alkyl ester derivatives, methacrylic acid and salts thereof, methacrylic acid alkyl ester derivatives, and ethylene glycol dimethacrylate.
