Title:
PHOTOSETTING COMPOSITION, THREE-DIMENSIONALLY SHAPED ARTICLE, MOLD, METHOD FOR MANUFACTURING CURED PRODUCT, AND METHOD FOR MANUFACTURING PLATE DENTURE
Document Type and Number:
WIPO Patent Application WO/2023/190071
Kind Code:
A1
Abstract:
This photosetting composition comprises a (meth)acrylic monomer component and a photoinitiator. When a cured layer A1 having a thickness of 50 µm is obtained by irradiating the photosetting composition with visible light having a wavelength of 405 nm at an irradiation quantity of 11 mJ/cm2, a rectangular plate-like shaped article A1 having a length of 40 mm, a width of 10 mm, and a thickness of 1.0 mm is obtained by layering the cured layer A1 in the thickness direction, and a rectangular plate-like test piece A1 having a length of 40 mm, a width of 10 mm, and a thickness of 1.0 mm is prepared through optical shaping by irradiating the shaped article A1 with ultraviolet rays having a wavelength of 365 nm at an irradiation quantity of 3 J/cm2, the storage modulus of the test piece A1 at 25°C is 10 MPa or more and the storage modulus of the test piece A1 at 37°C is 400 MPa or less.
