Abstract:
1. A photo-curable composition for forming a three-dimensional pattern by a photo-imprinting method, characterized by comprising: a monomer having a photopolymerizable group, the photopolymerizable group being at least one organic group selected from the group consisting of an acryl group, a methacryl group, a vinyl group, an epoxy group, an oxetane group, and a vinyl ether group, wherein the monomer contains a monofunctional monomer, a difunctional monomer, and a trifunctional monomer in a mass ratio of monofunctional monomer:difunctional monomer:trifunctional monomer equal to 1:0.2 to 2.0:0.2 to 2.0, and the monofunctional monomer is a cyclic amine-containing acrylate monomer; an inorganic fine particle, wherein a dispersant is added to the inorganic fine particle and wherein the dispersant is a silane coupling agent; and a photopolymerization initiator.
