PHOTOCURABLE COMPOSITION, THREE-DIMENSIONAL MODELING PRODUCT, MOLD, METHOD OF PRODUCING CURED PRODUCT, AND METHOD OF PRODUCING PLATE DENTURE

Abstract: a photocurable composition, contains a (meth)acrylic monomer component, and photopolymerization initiator, in a case in which a rectangular sheet-like test piece a1 with a length of 40 mm, a width of 10 mm, and a thickness of 1.0 mm is produced by photomodeling under conditions in which the photocurable composition is irradiated with visible light having a wavelength of 405 nm at an irradiation dose of 11 mj/cmto form a cured layer a1 with a thickness of 50 �m, the cured layer a1 is stacked in a thickness direction thereof to form a rectangular sheet-like modeling product a1 with a length of 40 mm, a width of 10 mm, and a thickness of 1.0 mm, and the modeling product a1 is irradiated with ultraviolet rays having a wavelength of 365 nm at an irradiation dose of 3 j/cmto produce the test piece a1.
