A water-based curable composition comprising: a water-soluble photopolymerization initiator having an acylphosphine oxide structure in which an aromatic acyl group bonded to the phosphorus atom has one or more carbonyl groups directly bonded to the aromatic ring; water; and a polymerizable compound. The water-soluble photopolymerization initiator is novel and is a compound represented by formula 1-1 or formula 2-1. La présente invention concerne une composition durcissable aqueuse comprenant : un initiateur de photopolymérisation hydrosoluble ayant une structure d'oxyde d'acylphosphine, un groupe acyle aromatique lié à l'atome de phosphore ayant au moins un groupe carbonyle directement lié au cycle aromatique; de l'eau; et un composé polymérisable. L'initiateur de photopolymérisation soluble dans l'eau est nouveau et est un composé représenté par la formule 1-1 ou la formule 2-1. 水性硬化性組成物は、アシルホスフィンオキシド構造におけるリン原子に結合する芳香族アシル基の芳香環に更に１つ以上のカルボニル基が直接結合した構造を有する水溶性光重合開始剤、水、及び、重合性化合物を含む。また、新規な水溶性光重合開始剤は、式１－１又は式２－１で表される化合物である。
