Title (EN) LAMINATE AND SEALING MEMBER USING SAME
(FR) STRATIFIÉ ET ÉLÉMENT D'ÉTANCHÉITÉ L'UTILISANT
(JA) 積層体およびそれを用いた封止部材
Abstract:
(EN) Provided is a laminate which sequentially comprises, on at least one surface of a substrate film, an inorganic compound layer and a protective layer in this order from the substrate film side. This laminate is characterized in that: the protective layer contains a vinyl alcohol resin; and the vinyl alcohol resin contains a cyclic compound structure that has a carbonyl group in a cyclic structure. This laminate has excellent oxygen and water vapor barrier properties even after a high-temperature hydrothermal treatment.
(FR) L'invention concerne un stratifié qui comprend séquentiellement, sur au moins une surface d'un film de substrat, une couche de composé inorganique et une couche protectrice, dans cet ordre à partir du côté film de substrat. Ce stratifié est caractérisé en ce que : la couche protectrice contient une résine d'alcool vinylique ; et la résine d'alcool vinylique contient une structure de composé cyclique ayant un groupe carbonyle dans une structure cyclique. Ce stratifié présente d'excellentes propriétés de barrière à l'oxygène et à la vapeur d'eau, y compris après un traitement hydrothermique à haute température.
(JA) 基材フィルムの少なくとも一方の側に、無機化合物層と保護層とを基材フィルム側からこの順に有する積層体であって、該保護層がビニルアルコール系樹脂を含有し、該ビニルアルコール系樹脂が環状構造中にカルボニル基を有する環式化合物構造を含有することを特徴とする積層体。 高温熱水処理後でも優れた酸素および水蒸気バリア性を有する積層体を提供する。
