Zusammenfassung:To provide a two liquid type curable composition having good initial moldability (pot life) and, even at ordinary temperature, good curability (monomer conversion).SOLUTION: Provided is a two liquid type curable composition, comprising: liquid A including (i) a radically polymerizable monomer and (ii) at least one compound selected from heterocyclic ring-containing compounds, amino group-substituted aromatic ring-containing compounds, formyl group-substituted aromatic ring-containing compounds, compounds having alkanolamine skeletons, thiourea structure-containing compounds, and metal salts of carboxylic acids; and liquid B including (iii) a peroxide represented by R1-C(=O)-O-O-C(=O)-R2 (where R1 and R2 each independently represent an organic group having a carbon number of 1 to 20). At least one of the liquid A and the liquid B comprises at least one polymer selected from the group consisting of (iv) (meth)acrylic polymers, polyester-based polymers, polyurethane-based polymers, and silicone polymers.SELECTED DRAWING: None 【課題】 良好な初期成形性(ポットライフ)を有し、常温でも良好な硬化性(単量体転化率)を有する二液型硬化性組成物を提供することを目的とする。【解決手段】(i)ラジカル重合性モノマーと、(ii)複素環含有化合物、アミノ基置換芳香環含有化合物、ホルミル基置換芳香環含有化合物、アルカノールアミン骨格を有する化合物、チオ尿素構造含有化合物、およびカルボン酸の金属塩から選択される少なくとも1種の化合物、とを含むA液と、(iii)R1ーC(=O)ーOーOーC(=O)ーR2で表される過酸化物(ただし、R1、R2は、それぞれ独立に炭素数1~20の有機基を表す)を含むB液とを含み、A液およびB液の少なくとも一方は、(iv)(メタ)アクリル系ポリマー、ポリエステル系ポリマー、ポリウレタン系ポリマーおよびシリコーンポリマーからなる群より選択される少なくとも1種のポリマーを含む、二液型硬化性組成物である。【選択図】なし
