Zusammenfassung:	To provide a curable composition for models that yields a cured product with superior elongation recovery and whitening prevention.SOLUTION: A curable composition for models contains a 2-cyanoacrylate compound whose homopolymerized cured product has a storage modulus of 1.0×105 Pa or more and 1.0×107 Pa or less at 25°C (excluding diethylene glycol monoethyl ether cyanoacrylate), or contains a 2-cyanoacrylate compound whose homopolymerized cured product has a storage modulus of more than 1.0×107 Pa and 5.0×107 Pa or less at 25°C, and a polyfunctional cyanoacrylate compound.SELECTED DRAWING: None 【課題】硬化物の伸長回復率及び白化防止性に優れる模型用硬化性組成物の提供。【解決手段】単独重合してなる硬化物の２５℃における貯蔵弾性率が１．０×１０５Ｐａ以上１．０×１０７Ｐａ以下である２－シアノアクリレート化合物（ジエチレングリコールモノエチルエーテルシアノアクリレートを除く）を含有する、又は、単独重合してなる硬化物の２５℃における貯蔵弾性率が１．０×１０７Ｐａより大きく５．０×１０７Ｐａ以下である２－シアノアクリレート化合物と、多官能シアノアクリレート化合物とを含有する、模型用硬化性組成物。【選択図】なし
