Patent ID: 7754781

Claim:
An active energy beam-curable composition consisting essentially of: an ethylenically unsaturated group-containing component (A) that consists essentially of, as an essential component, a compound (A-1) having an ethylenically unsaturated group and an aromatic group; and a granular substance (B) that is insoluble in the component (A), in which the subtraction of the refractive index of the component (B) from the refractive index of a cured product of the component (A) alone is not less than 0.03 and not more than 0.18, the component (B) is a plastic; wherein the compound (A-1) consists essentially of a di(meth)acrylate (A-1) represented by the following formula (1): wherein, in the formula (1), X represents —C(CH 3 ) 2 — or S, R 1 and R 3 each independently represent a hydrogen atom or a methyl group, R 2 and R 4 each independently represent a hydrogen atom, a methyl group or an ethyl group, and l and m are each independently an integer of 0 to 4.
