Zusammenfassung:PROBLEM TO BE SOLVED: To provide a light-transmitting laminate film that can be applied to a member excellent in flexibility such as paper products or fabric products and has good heat insulating property, scratch resistance and interlayer adhesiveness.SOLUTION: A light-transmitting laminate film 10 includes a metal-containing layer (excluding a silver-containing layer) 14 containing metal or a metal oxide, a silver-containing layer 16 containing silver or a silver alloy, and a pressure-sensitive adhesive layer 18, in this order on one surface of a polyolefin film 12, and includes a hard coat layer 20 made of an organic-inorganic hybrid material on the other surface of the polyolefin film 12. An adhesive force between the polyolefin film 12 and the metal-containing layer (excluding a silver-containing layer) 14, measured in accordance with JIS A5759, is 50 mN/25 mm or more. 【課題】紙製品や布製品などの柔軟性に優れる部材に適用でき、良好な断熱性、耐擦傷性、層間密着性を有する光透過性積層フィルムを提供する。【解決手段】ポリオレフィンフィルム12の一方面上に、金属または金属酸化物を含有する金属含有層(銀含有層を除く)14と、銀または銀合金を含有する銀含有層16と、粘着剤層18と、をこの順で有し、ポリオレフィンフィルム12の他方面上に、有機無機ハイブリッド材料からなるハードコート層20を有し、ポリオレフィンフィルム12と金属含有層(銀含有層を除く)14との間のJIS A5759に準拠して測定される密着力が50mN/25mm以上である光透過性積層フィルム10とする。【選択図】図1
