METHOD FOR PRODUCING ARTICLE HAVING FINE CONCAVO-CONVEX STRUCTURE ON SURFACE

摘要

The present invention relates to a method for preparing an article having an uneven microstructure on a surface thereof, including 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 including a mold release agent, in which the mold release agent includes one or more kinds of phosphoric ester compound and the pH of the aqueous solution when extracted with 50 mL of water with respect to 1 g of the mold release agent is 3.0 or more; and
(II) a step of, after the step (I), interposing an active energy ray curable resin composition including a polymerizable compound, a polymerization initiator, and an internal release agent between the mold and the substrate, and curing the active energy ray curable resin composition by the irradiation with active energy rays to form a cured resin layer having the uneven microstructure transferred thereto on a surface of the substrate, thereby obtaining an article having an uneven microstructure on a surface thereof.
