Abstract
An active energy beam-curable composition includes a photo-cationic polymerizable substance; a photo-cationic polymerization initiator; and a polymerizable compound having an ethylenic unsaturated double bond such as monomethacrylate, dimethacrylate, monoacrylate, and diacrylate. Owing to the compound having the ethylenic unsaturated double bond contained in the composition, it is possible to suppress the occurrence of odor and cloudiness even when the composition is heated after being cured.
Claims15
An active energy beam-curable composition comprising:
- a photo-cationic polymerizable substance;
- a photo-cationic polymerization initiator;
- limonene dioxide;
- and
- a polymerizable compound having an ethylenic unsaturated double bond,
- wherein a weight ratio of a total weight of the limonene dioxide and the polymerizable compound having an ethylenic unsaturated double bond to a weight of the photo-cationic polymerizable substance is 7:3 to 8:2.
