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

WIPO Patent Application WO/2012/161315

A1

The present invention relates to a method for producing an article having a concavo-convex structure on its surface, the method comprising the following steps (I) and (II). (I) is a step for coating a molded surface comprising a fine concavo-convex structure made of anodized alumina, by a release solution containing a mold releasing agent, wherein the mold releasing agent contains at least one phosphoric ester compound, and when 1 g of the mold releasing agent is extracted by 50 mL of water, the aqueous solution has a pH of 3.0 or more. (II) is a step after the step (I), wherein an active energy ray curing resin composition containing a polymerizable compound, a polymerization initiator, and an internal releasing agent is held between the mold and a substrate, an active energy ray is irradiated thereto to cure the composition, and a cured resin layer to which the fine concavo-convex structure is transferred is formed on the surface of the substrate, to thereby obtain an article having a fine concavo-convex structure on its surface.
