Abstract:
1. A production method for a product having a cured resin layer with a fine concave-convex structure formed on a surface of a substrate, the method comprising filling a space between a mold having a fine concave-convex structure composed of anodized alumina on a surface thereof 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 a surface of the substrate, wherein (A) the method comprises treating a surface of the mold with a release agent, at least at transfer initiation, (B) the active energy ray-curable resin composition comprises a polymerizable compound, a polymerization initiator, and a (poly)oxyethylene alkyl phosphate ester compound, and an average spacing between convex protrusions or concave recesses of the fine concave-convex structure is not more than 400 nm.
