PROBLEM TO BE SOLVED: To provide a photocurable artificial nail composition that, by curing with visible light, heat generation during curing is suppressed, odor is reduced, the occurrence of sunburn can be prevented, and the composition has low skin irritation, and furthermore, after coating, by curing both an interior and a surface, a strong film is obtained and is not broken, there is no need for sanding against the nail surface of the user himself/herself, adhesion to the nail is high, and wrinkles are prevented from occurring on the surface.SOLUTION: The photocurable artificial nail composition contains a photopolymerizable compound, and (A) oligo α-hydroxyketone-based initiator, and (B) an acylphosphine oxide-based photopolymerization initiator.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】光硬化性人工爪組成物において、可視光により硬化させることにより、硬化時の発熱を抑制し、臭気を低減し、日焼けの発生を防止でき、かつ皮膚刺激性が低い組成物を得、さらに被覆後においては、内部及び表面共に硬化されることにより、強固な被膜を得て欠けることがなく、また使用者自身の爪表面に対してサンディングを行う必要がなく、かつ爪への密着性が高く、その表面にシワが発生することを防止する。【解決手段】光重合性化合物と(A)オリゴαヒドロキシケトン系開始剤と(B)アシルフォスフィンオキシド系光重合開始剤を含有する光硬化性人工爪組成物。【選択図】なし
