To obtain an active energy ray-curable composition having excellent curability and excellent adhesivity by mixing an amine-modified compound with one or more other polymerizable unsaturated compounds, wherein the amine-modified compound is obtained by reacting a specific (meth)acrylic compound with a specified vinyl ether-based compound to obtain a reactive hemiacetal ester, and subsequently adding a specific amine to the (meth)acryloyl group of the obtained reactive hemiacetal ester.
This active energy ray-curable composition comprises (E) an amine-modified compound and (F) one or more other polymerizable compounds. The components E is obtained by reacting (A) a (meth)acrylic compound having a carboxyl group with (B) a vinyl ether-based compound having two or more vinyl ether groups (for example, ethylene glycol divinyl ether) to obtain (C) a reactive hemiacetal ester, preferably a compound of the formula [R1 is H or methyl; R2 is a direct bond or the like; R3 is an organic residue; (x1) is 1 or 2; (x2) is 1-3; (x3) is 1-4; (x4) is 1-6], and subsequently adding (D) a primary or secondary amine (for example, pyrrole) to the (meth)acryloyl group of the reactive hemiacetal ester C.
