Abstract
(EN)
A purpose of the present invention is to provide a sealing agent for display elements, which has excellent flexing responsiveness. Another purpose of the present invention is to provide: a cured product of this sealing agent for display elements; and a vertically conducting material and a display element, each of which uses this sealing agent for display elements. The present invention is a sealing agent for display elements, which contains a curable resin and a polymerization initiator and/or a thermal curing agent, and which enables the achievement of a cured product that has a storage elastic modulus at 25°C of less than 0.8 GPa and a glass transition temperature of 25°C or less. In addition, a cured product of this sealing agent for display elements, which has a thickness of 500 μm, has a water vapor permeability of 120 g/m2∙24 hr or less in an environment at 60°C at 90% RH as determined in accordance with JIS Z 0208.

Un but de la présente invention est de pourvoir un agent d'étanchéité pour éléments d'affichage qui présente une excellente sensibilité à la flexion. Un autre but de la présente invention est de fournir un produit durci de l'agent d'étanchéité pour les éléments d'affichage, un matériau conducteur vertical et un élément d'affichage, chacun utilisant l'agent d'étanchéité pour les éléments d'affichage. La présente invention concerne un agent d'étanchéité pour éléments d'affichage qui contient une résine durcissable et un amorceur de polymérisation et/ou un agent de durcissement thermique et qui permet d'obtenir un produit durci ayant un module d'élasticité de stockage à 25°C inférieur à 0,8 GPa et une température de transition vitreuse de 25°C ou moins. De plus, un produit durci de cet agent d'étanchéité pour des éléments d'affichage, qui a une épaisseur de 500 µm, a une perméabilité à la vapeur d'eau de 120 g/m2∙24 h ou moins dans un environnement à 60°C à 90 % HR telle que déterminée conformément avec la norme JIS Z 0208.
