Abstract:
1. A method for preparing an article having an uneven microstructure on a surface thereof, comprising the following steps (I) and (II): (I) a step of coating a surface of a mold having an uneven microstructure formed from an anodized alumina oxide on a surface thereof with a release treatment solution comprising a mold release agent, where the mold release agent consists of one or more (poly)oxyalkylene alkyl phosphoric ester compounds, where the pH of an aqueous solution resulting from extraction of 1 g of the mold release agent with 50 mL of water is 3.0 or more; and (II) a step of, after the step (I), interposing an active energy ray curable resin composition comprising a polymerizable compound, a polymerization initiator, and an internal release agent between the mold and a substrate, and curing the active energy ray curable resin composition by irradiating the composition with active energy rays to form a cured resin layer having the uneven microstructure transferred thereto on the surface of the substrate, thereby obtaining an article having an uneven microstructure on a surface thereof, wherein the (poly)oxyalkylene alkyl phosphoric ester compound is of a formula (1) wherein R
