Abstract:
(EN) The purpose of the present invention is to provide a photocurable resin composition which exhibits high curability with respect to visible light if used, for example, as a liquid crystal sealing agent, and which is capable of highly suppressing liquid crystal contamination. A photocurable resin composition according to the present invention contains: a curable compound A that has an ethylenically unsaturated double bond in each molecule; and a compound B that has one or more NHCO groups and an anthraquinone skeleton or a thioxanthone skeleton in each molecule, while having an NHCO group equivalent represented by formula (I) of 350 g/eq or less. Formula (I): NHCO group equivalent (g/eq) = (molecular weight)/(number of NHCO groups contained in one molecule)
(FR) L'objectif de la présente invention est de proposer une composition de résine photodurcissable qui présente une aptitude élevée au durcissement par rapport à la lumière visible si on l'utilise, par exemple, en tant qu'agent d'étanchéité pour cristaux liquides, et qui est capable de supprimer de façon importante la contamination des cristaux liquides. L'invention concerne une composition de résine photodurcissable qui contient : un composé durcissable A qui possède une liaison double à insaturation éthylénique dans chaque molécule ; et un composé B qui possède au moins un groupe NHCO et un squelette anthraquinone ou un squelette thioxanthone dans chaque molécule, tout en ayant un équivalent de groupe NHCO représenté par la formule (I) de 350 g/éq ou moins. Formule I : équivalent de groupe NHCO (g/éq.) = (poids moléculaire)/(nombre de groupes NHCO contenus dans une molécule).
(JA) 本発明の目的は、例えば液晶シール剤として用いた際に、可視光に対する硬化性が高く、かつ液晶汚染を高度に抑制できる光硬化性樹脂組成物を提供することである。本発明の光硬化性樹脂組成物は、分子内にエチレン性不飽和二重結合を有する硬化性化合物Aと、分子内にアントラキノン骨格又はチオキサントン骨格と、1以上のNHCO基とを有し、式(I)で表されるNHCO基当量が350g/eq以下である化合物Bとを含む。 NHCO基当量(g/eq)=分子量/1分子に含まれるNHCO基の数・・・式(I)
