CURABLE RESIN COMPOSITION, CONCRETE COATING COMPOSITION AND LINING MATERIAL
PROBLEM TO BE SOLVED: To provide a curable resin composition excellent in low odor and durability, a lining material and a concrete coating composition.SOLUTION: A curable resin composition contains (A) urethane(meth)acrylate having at least two or more (meth)acryloyl groups in the molecular terminal, (B) epoxy(meth)acrylate which is formed of a reactant of an aromatic epoxy resin and a (meth)acrylic acid, has a number average molecular weight of 500-1,100 and an acid value of 10 KOHmg/g or less, (C) ethoxylated bisphenol A di(meth)acrylate having an ethylene oxide addition molar number of 2-10, (D) a monofunctional (meth)acrylate monomer having a group containing a cyclic hydrocarbon group having only one carbon-carbon double bond or nitrogen atom in the cycle as an alcohol residue having a molecular weight of 300 or less, and (E) a (meth)acrylate monomer having a phenyl group.SELECTED DRAWING: None
【課題】低臭気、耐久性等に優れた硬化性樹脂組成物、ライニング材及びコンクリート被覆組成物を提供する。【解決手段】本発明は、（Ａ）分子末端に少なくとも２個以上の（メタ）アクリロイル基を有するウレタン（メタ）アクリレ−ト、（Ｂ）芳香族系エポキシ樹脂と（メタ）アクリル酸との反応物からなり、数平均分子量が５００〜１１００の範囲にあって、酸価が１０ＫＯＨｍｇ／ｇ以下のエポキシ（メタ）アクリレ−ト、（Ｃ）エチレンオキサイド付加モル数２〜１０のエトキシ化ビスフェノ−ルＡジ（メタ）アクリレ−ト、及び、（Ｄ）分子量が３００以下のアルコ−ル残基として環内に炭素間二重結合又は窒素原子を１個のみを有する環状炭化水素基を含む基を有する単官能性（メタ）アクリレ−ト系モノマ−を含み、（Ｅ）フェニル基を有する（メタ）アクリレ−トモノマ−とを含む硬化性樹脂組成物である。【選択図】なし
