Title (EN) PHOTOCURABLE COMPOSITION
(FR) COMPOSITION PHOTODURCISSABLE
(JA) 光硬化性組成物
Abstract:
(EN) [Problem] Conventionally, it has been difficult to form a colorless transparent cured product from a photocurable composition comprising a UV absorber because the UV absorber itself is colored. Thus, it has been difficult to use such a photocurable composition in a display device for which colorless transparency is required. [Solution] A photocurable composition comprising a specific compound, wherein a cured product having a thickness of 200 μm or less has a light transmittance at 385 nm of 50% or less in a state of being sandwiched between 0.7 mm-thick alkali-free glass sheets and a yellowness of 3.0 or less.
(FR) Le problème décrit par la présente invention est que, de manière classique, il était difficile de former un produit durci transparent incolore à partir d'une composition photodurcissable comprenant un absorbeur UV étant donné que l'absorbeur UV lui-même est coloré. Ainsi, il était difficile d'utiliser une telle composition photodurcissable dans un dispositif d'affichage pour lequel une transparence incolore est requise. La solution selon l'invention porte sur une composition photodurcissable comprenant un composé spécifique, un produit durci ayant une épaisseur de 200 µm ou moins a une transmittance de lumière à 385 nm de 50 % ou moins lorsqu'il est pris en sandwich entre 0,7 mm de feuilles de verre sans alcali et un jaunissement inférieur ou égal à 3,0.
(JA) 【課題】従来、紫外線吸収剤を添加した光硬化性組成物では、紫外線吸収剤自体に色がついていることから無色透明な硬化物を形成することが難しく、無色透明が求められる表示装置に用いることが困難であった。 【解決手段】特定の化合物を含む光硬化性を有する組成物であり、200μm以下の厚さの硬化物において0.7mm厚の無アルカリガラス板で挟んだ状態での385nmの光透過率が50%以下であると共に黄色度が3.0以下である光硬化性組成物である。
