Title:
PHOTOPOLYMERIZABLE COMPOSITION, THREE-DIMENSIONAL MOLDED ARTICLE, AND DENTAL PRODUCT
Document Type and Number:
WIPO Patent Application WO/2021/193962
Kind Code:
A1
Abstract:
This photopolymerizable composition includes a photopolymerizable component and a photoinitiator. In a case in which a cured layer A1 having a thickness of 50 μm is formed by irradiating the photopolymerizable composition with visible light having a wavelength of 405 nm at an irradiation amount of 12 mJ/cm2, a rectangular plate-like molded article A1 having a length of 40 mm, a width of 10 mm, and a thickness of 1 mm is formed by stacking the cured layer A1 in the thickness direction, and a rectangular plate-like sample piece A1 having a length of 40 mm, a width of 10 mm, and a thickness of 1 mm is fabricated by stereolithography under a condition of irradiating the molded article A1 with ultraviolet light having a wavelength of 365 nm at an irradiation amount of 10 J/cm2, an X-ray absorption coefficient of the sample piece A1 is from 9.0 cm-1 to 34.0 cm-1.
