Abstract:
(EN) Provided is an optical laminate that can excel in external appearance. This optical laminate includes: a substrate film that includes an acrylic resin; and a surface treatment layer that is formed on one side of the substrate film, wherein among components that make up a position at a depth of 3.0μm from a substrate film side in the direction of the surface treatment layer, the proportion of acrylic resin components that have migrated into the surface treatment layer is 18% or greater.
(FR) L’invention concerne un corps optique stratifié excellent en terme d’apparence. Plus spécifiquement, le corps optique selon l’invention comporte un film de base contenant une résine acrylique et une couche traitée en surface formée sur un côté du film de base. La proportion de constituant de résine acrylique éluée dans la couche traitée en surface, dans une position située à une profondeur de 3,0 μm à partir du côté film de base en direction de la couche traitée en surface, est supérieure ou égale à 18%.
(JA) 外観に優れ得る光学積層体を提供する。本発明の光学積層体は、アクリル系樹脂を含有する基材フィルムと、基材フィルムの片側に形成された表面処理層と、を含み、基材フィルム側から表面処理層の方向に3.0μmの深さの位置を構成する成分のうち表面処理層に溶出したアクリル系樹脂の成分の割合が18%以上である。
