Abstract
Provided are an active energy ray-curable composition which has a viscosity suitable for coating and also has a super high refractive index at a level higher than ever, a cured product thereof, and a plastic lens. The active energy ray-curable composition contains zirconium oxide nanoparticles (A) and a bicarbazole compound (B) represented by the following structural formula (1) (in the formula, X1 and X2 each independently represent a photopolymerizable functional group, a structural moiety having a photopolymerizable functional group, or a hydrogen atom, provided that at least one of X1 and X2 represents a photopolymerizable functional group or a structural moiety having a photopolymerizable functional group; and R1 and R2 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a bromine atom, or a chlorine atom).
