FILM-FORMING COMPOSITION FOR OPTICAL IMPRINT AND METHOD FOR PRODUCING OPTICAL MEMBER

摘要

PURPOSE: A film-forming composition for an optical imprint does not need to remove organic solvent by prebaking the composition after coating and has high reflectivity. CONSTITUTION: A film-forming composition for an optical imprint contains a photopolymerizable monomer with a hydrophilic group, an inorganic nanoparticle, and a photopolymerization initiator. The content of the organic solvent is 20 wt% or less. The content of the photopolymerizable monomer with a viscosity of 500 cP or less is 30 wt% or greater to the total weight of the photopolymerizable monomer and the inorganic nanoparticle, and the refractivity of the monomer after curing is 1.56 or higher. A manufacturing method of an optical member comprises a step of forming a coating layer by spreading the film-forming composition on a substrate and mold-pressing the coating layer without heating; a step of curing the coating layer by a UV-irradiation to form a resin layer; and a step of separating the mold from the resin layer.
