Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an infrared reflection film simultaneously achieving heat sealability, visible light transmissivity and durability.SOLUTION: A method uses a first laminate film (10) having a first metal layer (15) on a first transparent film base material (11) and a second laminate film (20) having a second metal layer (25) on a second transparent film base material (21). An adhesive layer (30) of 40-200 nm thick is formed on a surface of a first metal layer formation side of the first laminate film (10) or a surface of a second metal layer formation side of the second laminate film (20), and the first metal layer formation surface of the first laminate film and the second metal layer formation surface of the second laminate film are bonded to face with each other interposing the adhesive layer (30).SELECTED DRAWING: Figure 1
【課題】遮熱性、可視光透過性および耐久性を兼ね備える赤外線反射フィルムを提供する。【解決手段】本発明の方法では、第一透明フィルム基材(11)上に第一金属層(15)を備える第一積層フィルム(10)と、第二透明フィルム基材(21)上に第二金属層(25)を備える第二積層フィルム(20)が用いられる。第一積層フィルム(10)の第一金属層形成側の表面または第二積層フィルム(20)の第二金属層形成側の表面に、40nm〜200nmの厚みを有する接着剤層(30)を形成し、第一積層フィルムの第一金属層形成面と、第二積層フィルムの第二金属層形成面とが、接着剤層(30)を介して対向するように貼り合せられる。【選択図】図1 |
