An active energy beam-curable composition includes a photo-cationic polymerizable substance; a photo-cationic polymerization initiator; and an oxetane compound such as 3-ethyl-3-hydroxymethyloxetane, di[1-ethyl(3-oxetanyl)]methyl ether, and 3-ethyl-3-(2-ethylhexyloxymethyl)oxetane. Owing to the oxetane compound contained in the composition, it is possible to suppress the occurrence of odor and cloudiness even when the composition is heated after being cured. |
