Claim 0:
1. A photocurable composition comprising a photopolymerizable component and a photopolymerization initiator, wherein:
in a case in which a test piece P1 with a length of 39 mm, a width of 8 mm, and a thickness of 4 mm, is produced by photofabrication under conditions in which the photocurable composition is irradiated with visible light having a wavelength of 405 nm at an irradiation dose of 12 mJ/cm2 to form a cured layer P1 with a thickness of 100 m, the cured layer P1 is stacked in a thickness direction thereof to form a rectangular fabrication product P1 with a length of 39 mm, a width of 8 mm, and a thickness of 4 mm, and the fabrication product P1 is irradiated with ultraviolet rays having a wavelength of 365 nm at an irradiation dose of 10 J/cm2 to produce the test piece P1, a total fracture work of the test piece P1 measured in compliance with ISO20795-1:2008 is 1100 J/m2 or more;
wherein the photopolymerizable component comprises:
a di(meth)acrylic monomer (A) having two (meth)acryloyloxy groups and two urethane bonds; and
an acrylic monomer (B) having one acryloyl group; and
wherein di(meth)acrylic monomer (A) comprises a compound represented by the following Formula (1),, wherein, in Formula (1), R1 is a divalent chain hydrocarbon group, a divalent hydrocarbon group with an aromatic structure, or a divalent hydrocarbon group with an alicyclic structure: each of R2 and R3 is independently a divalent chain hydrocarbon group that may have a substituent; and each of R4 and R5 is independently a methyl group or a hydrogen atom.
