膜及包含该膜的夹层玻璃用中间膜
摘要：
本发明提供含有选自聚乙烯醇缩醛树脂、聚乙烯乙酸乙烯酯共聚树脂、聚氨酯树脂、聚酯树脂和聚丙烯酸系树脂中的至少1种热塑性树脂(A)，并且含有平均粒径为200nm以下的铜化合物(B)的微粒的膜。该膜由于透明性、隔热性、电磁波透过性和耐久性优异，适合用于夹层玻璃用中间膜。
摘要（英）：

A film is provided that is formed of at least one kind of a thermoplastic resin (A), selected from the group consisting of a polyvinyl acetal resin, a polyethylene vinyl acetate copolymer resin, a polyurethane resin, a polyester resin, and a polyacrylic resin, and contains microparticles of a copper compound (B) having an average particle diameter of 200 nm or less. The film is excellent in transparency, a heat-shielding property, electromagnetic wave permeability, and durability, so that it is suitable to be an interlayer film for laminated glass.
