摘要： [Problem]
To provide a photocurable composition having a high curing depth.
[Solution]
To provide a photocurable composition of the present disclosure comprises (A) polymerizable monomer, (B) photosensitizer, (C) photoacid generator, and (D) photopolymerization accelerator, wherein, the photocurable composition comprises (D-1) amine compound represented by formula (1) as the (D) photopolymerization accelerator. (In the formula (1), R1 is a substituent represented by formula (2), and R2 and R3 are substituents represented by formula (2) or substituents selected from —OH group, —O— group, —S— group, —NH—C(O)—NH— group, —C(O)—O— group, —OC(O)— group, —OC(O)—NH— group, —NH—C(O)—O— group, halogen, an organic group which may have an alkoxysilyl group, an aromatic ring which may have a substituent and an alicyclic heterocycle which may have a substituent. Further, R2 and R3 may be H when at least one or more R4s of the formula (2) are an aromatic ring, and R3 may be H when R2 is a substituent represented by the formula (2)).
