Abstract
The present invention relates to a production method for a product having a cured resin layer with a fine concave-convex structure formed on the surface of a substrate, the method including filling the space between a mold having a fine concave-convex structure composed of anodized alumina on the surface and a substrate with an active energy ray-curable resin composition, and curing the composition by irradiation with active energy rays, thereby forming a cured resin layer into which the fine concave-convex structure has been transferred on the surface of the substrate, wherein (A) the method includes treating the surface of the mold with a release agent, at least at transfer initiation, and (B) the active energy ray-curable resin composition includes a polymerizable compound, a polymerization initiator and a (poly)oxyethylene alkyl phosphate ester compound.
