Zusammenfassung: | To provide: a curable composition having a short cure time and high storage stability; a cured product using the same; and an article.SOLUTION: A curable composition comprises: a polyfunctional methylene malonic ester having two or more structural units represented by the following formula (I) and having two or more of the structural units linked together via a polyhydric alcohol residue; a compound having a first acid dissociation constant of 3 to 14 and a molecular weight of less than 500; and an acidic stabilizer. [In the formula, R1 and R2 are each independently a hydrogen atom or a univalent hydrocarbon group having 1 to 15 carbon atoms, where R1 and R2 may together form a bivalent hydrocarbon group having 3 to 15 carbon atoms.]SELECTED DRAWING: None
【課題】硬化時間が短く、且つ高い貯蔵安定性を有する硬化性組成物、並びにこれを用いた硬化物及び物品を提供すること。【解決手段】下記式(I)で表される構造単位を二つ以上有し、且つ二つ以上の前記構造単位が多価アルコールの残基で連結された多官能メチレンマロン酸エステルと、第1酸解離定数が3~14であり、且つ分子量が500未満である化合物と、酸性安定剤と、を含有する硬化性組成物。【化1】TIFF2022099020000011.tif29149[式中、R1及びR2は、それぞれ独立に、水素原子又は1~15個の炭素原子を有する1価の炭化水素基を示す。R1及びR2は、一緒になって3~15個の炭素原子を有する2価の炭化水素基を形成していてもよい。]【選択図】なし |
