| 主权项 | 1. A film-forming composition for optical imprint, comprising (A) a photopolymerizable monomer having a hydrophilic group, (B) inorganic nanoparticles, and (C) a photopolymerization initiator, the composition having an organic solvent content of 5 to 20% by mass, including a monomer which has a viscosity of 500 cP or less as component (A) at a proportion of 30% by mass or more relative to the total amount of component (A) and component (B), and having a refractive index after curing of 1.56 or higher as measured using light having a wavelength of 600 nm. | ||
