PROBLEM TO BE SOLVED: To provide an optical reflective film which is suitable for pasting on car windows and window glasses with water and allows for easily adjusting a position thereof when pasted with water.SOLUTION: An optical reflective film comprises a base material, a dielectric multilayer film disposed on one surface of the base material and comprising alternately laminated low refractive index layers and high refractive index layers, and an adhesive layer provided on a surface of the dielectric multilayer film opposite the substrate side. At least one layer of the low refractive index layers and high refractive index layers contains water-soluble resin, and the adhesive layer contains an adhesive agent and a polyether-modified silicone compound.SELECTED DRAWING: None 【課題】車窓、窓ガラス等への水貼りに適し、水貼り時の位置調整性が良好な光学反射フィルムを提供する。【解決手段】基材と、前記基材の一方の面上に配置された、低屈折率層と高屈折率層とが交互に積層されてなる誘電体多層膜と、前記誘電体多層膜の前記基材と反対側の面上に設けられる粘着層と、を有し、前記低屈折率層および前記高屈折率層のうち少なくとも１層は、水溶性樹脂を含み、前記粘着層は、粘着剤と、ポリエーテル変性シリコーン化合物とを含む、光学反射フィルムである。【選択図】なし
