Title (EN) RESIN COMPOSITION AND CURED PRODUCT SHEET
(FR) COMPOSITION DE RÉSINE ET FEUILLE DE PRODUIT DURCI
(JA) 樹脂組成物及び硬化物シート
Abstract:
(EN) The purpose of the present invention is to provide a resin composition for obtaining a cured product sheet which has excellent transparency, surface hardness, and scratch resistance, and can be suitably used as an alternative to a cover glass. The resin composition according to the present invention is characterized by containing (A) 3-20 wt% of a ladder-type or random-type silsesquioxane, (B) 30-90 wt% of a multifunctional urethane(meth)acrylate oligomer which is hexa- or higher functional and has a weight-average molecular weight of 1,000 or more, and (C) 5-60 wt% of a mono- to tri-functional (meth)acrylate monomer.
(FR) La présente invention vise à procurer une composition de résine permettant l'obtention d'une feuille de produit durci qui présente une excellente transparence, dureté de surface et résistance à la rayure, et peut être utilisée de façon appropriée en tant qu'alternative à un verre de couverture. La composition de résine selon la présente invention est caractérisée en ce qu'elle contient (A) 3 à 20 % en poids d'un silsesquioxane de type échelle ou de type aléatoire, (B) 30 à 90 % en poids d'un oligomère (méth)acrylate d'uréthane multifonctionnel qui est hexafonctionnel ou de fonctionnalité plus élevée et a un poids moléculaire moyen en poids de 1 000 ou plus, et (C) 5 à 60 % en poids d'un monomère (méth)acrylate monofonctionnel à trifonctionnel.
(JA) 本発明は、透明性、表面硬度及び耐擦傷性に優れ、カバーガラスの代替材料として好適に使用することができる硬化物シートを得るための樹脂組成物を提供することを目的とする。 本発明の樹脂組成物は、(A)ラダー型又はランダム型のシルセスキオキサンを3~20重量%、(B)6官能以上で重量平均分子量が1,000以上の多官能ウレタン(メタ)アクリレートオリゴマーを30~90重量%、及び、(C)1~3官能の(メタ)アクリレートモノマーを5~60重量%含有することを特徴とする。
