Kind Code:
A1
Abstract:
An active-energy-ray-curable composition including at least two or more kinds of polymerizable monomers (A) where a homopolymer of each of the polymerizable monomers (A) has a glass transition temperature of 80 degrees Celsius or more, wherein the polymerizable monomers (A) have a polymerizable monomer (A1) where a homopolymer of the polymerizable monomer (A1) has an SP value of 10.8 or more but 12.2 or less determined by a Fedors method, and an amount of the polymerizable monomer (A1) is 3% by mass or more but 20% by mass or less relative to a total amount of the active-energy-ray-curable composition.
