Document Type and Number:
WIPO Patent Application WO/2023/090302
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing: an active energy ray-curable composition which has various characteristics required for active energy ray-curable compositions, and which is especially capable of achieving high transparency, high curability with respect to LED rays, and resistance to curing shrinkage at the same time, the characteristics having been difficult to achieve at the same time; and a cured product which can achieve transparency, heat resistance, impact resistance, wear resistance, resistance to wet heat yellowing, water resistance and durability at the same time, the characteristics having been difficult to achieve at the same time. [Solution] The present invention provides an active energy ray-curable composition which contains a (meth)acrylate (A) that has a amide group and a cyclic substituent in each molecule, and a polymerizable compound (B) (excluding (A)) that has one or more ethylenically unsaturated groups in each molecule, and which contains, as the polymerizable compound (B), at least a polymerizable compound (b1) that has a chain substituent having 1 to 36 carbon atoms and/or a polymerizable compound (b2) that has a cyclic substituent having 3 to 20 carbon atoms.
