Abstract:
(EN) Provided is an adhesive composition comprising: component (A) a modified polyolefin resin, and component (B) a polyfunctional epoxy compound not having an aromatic ring, characterized in that when this adhesive composition is formed in a sheet form having a thickness of 10 µm, and when the cured sheet is subsequently is subjected to colorimetry, the b* value in the CIE L*a*b* standard colorimetric system stipulated by JIS Z 8729-1994 falls within the range of -2.0 to +2.0 inclusive. Also provided are an adhesive sheet having an adhesive layer formed using this adhesive composition, and a sealed body obtained by sealing an object to be sealed with this adhesive sheet. According to the present invention, it is possible to provide an adhesive composition which can be easily formed into sheet form, and which has excellent colorless transparency, an adhesive sheet having an adhesive layer formed using this adhesive composition, and a sealed body obtained by sealing an object to be sealed with the adhesive sheet.
(FR) L’invention concerne une composition d’adhésif qui comprend une résine à base de polyoléfine modifiée en tant que composant (A), et un composé époxy polyfonctionnel dépourvu de cycle aromatique en tant que composant (B). Cette composition d’adhésif est caractéristique en ce que lorsqu’elle est moulée en feuille de 10μm d’épaisseur, que la couleur de son produit durci est mesurée, la valeur b* dans le système couleur CIE L*a*b* défini dans JIS Z 8729-1994, est comprise entre -2,0 et +2,0. L’invention concerne également une feuille adhésive possédant une couche d’adhésif formée à l’aide de cette composition d’adhésif, et un corps de scellement constitué par scellement d’un objet à sceller au moyen de ladite feuille adhésive. Plus précisément, l’invention fournit une composition d’adhésif facilitant un moulage en feuille et se transformant en objet durci pourvu d’excellentes propriétés de transparence incolore, une feuille adhésive possédant une couche d’adhésif formée à l’aide de cette composition d’adhésif, et un corps de scellement constitué par scellement d’un objet à sceller au moyen de ladite feuille adhésive.
(JA) 本発明は、(A)成分:変性ポリオレフィン系樹脂、及び(B)成分:芳香環を有しない多官能エポキシ化合物を含有する接着剤組成物であって、この接着剤組成物を、厚さ10μmのシート状に成形し、次いで、これを硬化させたものを測色したときに、JIS Z 8729-1994に規定されるCIE L*a*b*表色系におけるb*値が、-2.0~+2.0であることを特徴とする接着剤組成物、この接着剤組成物を用いて形成された接着剤層を有する接着シート、及び被封止物が前記接着シートで封止されてなる封止体である。本発明によれば、シート状に成形し易く、かつ、無色透明性に優れる硬化物になる接着剤組成物、この接着剤組成物を用いて形成された接着剤層を有する接着シート、及び被封止物が前記接着シートで封止されてなる封止体が提供される。
