Abstract:
(EN) The present invention relates to a photocurable adhesive sheet containing an ultraviolet absorbing agent, and provides a novel adhesive sheet having ultraviolet-resistant foaming properties without compromising photocuring performance. Provided is an adhesive sheet characterized by having an adhesive layer formed from an adhesive composition containing an ultraviolet absorbing agent and a photoinitiator, the ultraviolet absorbing agent having an extinction coefficient of 1×103mL/(g∙cm) or greater at a wavelength of 340 nm and an extinction coefficient of less than 1×103mL/(g∙cm) at a wavelength of 380 nm, and the adhesive composition containing the ultraviolet absorbing agent at a ratio of 0.1-1.6% by mass with respect to the entire mass of the adhesive composition.
(FR) La présente invention concerne une feuille adhésive photodurcissable contenant un agent absorbant les ultraviolets, qui permet d'obtenir une nouvelle feuille adhésive ayant des propriétés moussantes résistant aux ultraviolets sans compromettre la performance de photodurcissement. La feuille adhésive selon l'invention est caractérisée en ce qu'elle comprend une couche adhésive formée à partir d'une composition adhésive contenant un agent absorbant les ultraviolets et un photo-initiateur, où l'agent absorbant les ultraviolets a un coefficient d'extinction de 1×103mL/(g∙cm) ou plus à une longueur d'onde de 340 nm et un coefficient d'extinction inférieur à 1×103mL/(g∙cm) à une longueur d'onde de 380 nm, et en ce que la composition adhésive contient ledit agent absorbant les ultraviolets dans un rapport de 0,1 à 1,6 % en poids par rapport au poids total de la composition adhésive.
(JA) 紫外線吸収剤を含有する光硬化型粘着シートに関し、光硬化性能を阻害することなく、耐紫外線発泡性を有する、新たな粘着シートを提供する。 紫外線吸収剤及び光開始剤を含有する粘着剤組成物から形成された粘着剤層を有し、前記紫外線吸収剤は、波長340nmでの吸光係数が1×10mL/(g・cm)以上であって、かつ、波長380nmでの吸光係数が1×10mL/(g・cm)未満であり、前記粘着剤組成物の全質量に対して0.1~1.6質量%の割合で紫外線吸収剤を含有することを特徴とする粘着シートを提案する。
