Abstract
Provided is an active energy ray curable composition cured by irradiation of active energy rays. The active energy ray curable composition contains an (A) radical polymerizable compound, a (B) photopolymerization initiator, and a (C) amine compound. The (B) photopolymerization initiator includes a (B1) sulfur compound and a (B2) acyl phosphine oxide compound. The (B1) sulfur compound is at least one of a sulfone compound and a thiobenzoyl compound.
