ACTIVE-ENERGY-RAY-CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/074620
Kind Code:
A1
Abstract:
[Problem] To provide: a highly transparent active-energy-ray-curable composition that has few residual unreacted substances or low-molecular decomposition products, that does not cause odor or bleed-out, that makes it possible to acquire a cured product having high safety, durability, and transparency, and that can be cured completely even by long-wavelength light having a wavelength of 350 nm or greater; and a molded article which has various applications and in which the aforementioned composition is used. [Solution] An active-energy-ray-curable composition that includes a polymerizable photoinitiator (A) having one or more benzophenone groups and one or more ethylenically unsaturated groups per molecule, and a polymerizable compound (B) (excluding A) having one or more ethylenically unsaturated groups per molecule, the amount of components having a molecular weight of less than 1000 in a cured product of the aforementioned composition being less than 10%.
