Abstract
An active energy ray curable composition is provided. The active energy ray curable composition includes polymerizable compounds including a first monofunctional monomer having a polar group, a second monofunctional monomer having no polar group, and a polyfunctional monomer. The homopolymer of each of the first monofunctional monomer and the second monofunctional monomer has a glass transition temperature of 50° C. or more. The first monofunctional monomer and the second monofunctional monomer account for 50% by mass or more of the polymerizable compounds in total, and the polyfunctional monomer accounts for 30% by mass or less of the polymerizable compounds.
