Document Type and Number:
WIPO Patent Application WO/2024/004861
Kind Code:
A1
Abstract:
The present invention can provide: an active energy ray-curable composition having good mold releasability and a high refractive index and low viscosity; and a cured product of the active energy ray-curable composition. The active energy ray-curable composition according to the present invention contains inorganic nanoparticles (A), a (meth)acrylate compound (B), and a photopolymerization initiator (C). The (meth)acrylate compound (B) contains a monofunctional (meth)acrylate (B1), the content of the monofunctional (meth)acrylate (B1) in the (meth)acrylate compound (B) is at least 70 mass%, and the mass blending ratio [(A)/(B1)] of the monofunctional (meth)acrylate (B1) to the inorganic nanoparticles (A) is in the range of 0.5-3.
