要約
(EN)

PROBLEM TO BE SOLVED: To provide a cationically-curable curable composition in which suppression of discoloration of a cured material during curing and good curability can be obtained at the same time, a cured material of the curable composition, and a method for forming a cured material using the curable composition.

SOLUTION: A curable composition including a cationic curing agent (A) and a cationically curable compound (B), wherein the cationic curing agent used includes a combination of a photoacid generator (A1) comprising an onium salt having a cation portion of a specific structure, and a thermal acid generator (A2) having as an anion portion a gallium-containing anion of a specific structure.

【課題】硬化時の硬化物の着色の抑制と、良好な硬化性とを両立できるカチオン硬化性の硬化性組成物と、当該硬化性組成物の硬化物と、当該硬化性組成物を用いる硬化物の形成方法とを提供すること。
【解決手段】カチオン硬化剤(A)と、カチオン硬化性化合物(B)とを含む硬化性組成物において、特定の構造のカチオン部を有するオニウム塩からなる光酸発生剤(A1)と、特定の構造の含ガリウムアニオンをアニオン部として有する熱酸発生剤(A2)とを組み合わせて含むカチオン硬化剤を用いる。
【選択図】なし
