Title (EN) LAYERED FILM
(FR) FILM STRATIFIÉ
(JA) 積層フィルム
Abstract:
(EN) A layered film (100) includes, in order, a first skin layer (110) formed from a thermoplastic resin S1, a core layer (120) formed from a thermoplastic resin C, and a second skin layer (130) formed from a thermoplastic resin S2. The first skin layer, the core layer, and the second skin layer have a specific relationship in the average absorption rate of light in a wavelength region of 9-11 μm. The glass transition temperature Tg(s1) of the thermoplastic resin S1 is 150°C or higher, the glass transition temperature Tg(s2) of the thermoplastic resin S2 is 150°C or higher, and the UV transmittance at a wavelength of 380 nm is 10% or lower.
(FR) L'invention concerne un film stratifié (100) comprenant, dans l'ordre, une première couche (110) de revêtement formée d'une résine thermoplastique S1, une couche (120) de cœur formée d'une résine thermoplastique C, et une seconde couche (130) de revêtement formée d'une résine thermoplastique S2. La première couche de revêtement, la couche de cœur et la seconde couche de revêtement ont une relation spécifique dans le taux moyen d'absorption de la lumière dans une région de longueur d'onde de 9 à 11 µm. La température de transition vitreuse Tg(s1) de la résine thermoplastique S1 est supérieure ou égale à 150°C, la température de transition vitreuse Tg(s2) de la résine thermoplastique S2 est supérieure ou égale à 150°C, et la transmittance des UV à une longueur d'onde de 380 nm est inférieure ou égale à 10%.
(JA) 積層フィルム(100)は、熱可塑性樹脂S1で形成された第1スキン層(110)、熱可塑性樹脂Cで形成されたコア層(120)、及び熱可塑性樹脂S2で形成された第2スキン層(130)を、この順に含み、前記第1スキン層、前記コア層及び前記第2スキン層は、9μm以上11μm以下の波長領域の光の平均吸収率において、特定の関係を有し、前記熱可塑性樹脂S1のガラス転移温度Tg(s1)が、150℃以上であり、前記熱可塑性樹脂S2のガラス転移温度Tg(s2)が、150℃以上であり、波長380nmの紫外線透過率が10%以下である。
