Abstract: Provided is an article having a micro uneven structure on a surface thereof, wherein the article is obtained by forming a micro uneven structure composed of a cured product of a solvent-free active energy ray curable resin composition on a substrate containing triacetylcellulose, wherein an average interval between two adjacent convex parts in the micro uneven structure is less than or equal to a visible light wavelength, and adhesion between the substrate containing triacetylcellulose and a layer composed of the cured product of the active energy ray curable resin composition is classified into any one of type 0 to 2 according to a crosscut method defined in ISO2409:1992 (JIS K 5600-5-6:1999).

Abstract: A method for preparing an article having an uneven microstructure on a surface thereof, including coating a surface of a mold having an uneven microstructure formed from an anodized alumina oxide on a surface with a release treatment solution including a mold release agent that 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 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 on a surface of the substrate.

Abstract: The present invention provides an active energy ray-curable resin composition comprising at least a multifunctional monomer having three or more radical polymerizable functional groups in the molecule in which the cured product of the composition exhibits anti-reflective function because of an uneven microstructure formed on the surface of the cured product, and provides a product having the uneven microstructure having high decontaminating properties such as fingerprint removal properties and high scratch resistance.
