Abstract: A plastic product includes a plastic base which has a surface and a synthetic polymer film provided on the surface of the plastic base, the surface of the plastic base being made of polycarbonate. The synthetic polymer film has raised portions whose two-dimensional size is in a range of more than 20 nm and less than 500 nm when viewed in its normal direction. A crosslink structure of the synthetic polymer film contains an ethylene oxide unit and a 2-(2-vinyloxy ethoxy)ethyl (meth)acrylate monomer unit. The proportion of the contained ethylene oxide unit to the entirety of the synthetic polymer film is not less than 35 mass % and less than 70 mass %. The proportion of the contained 2-(2-vinyloxy ethoxy)ethyl (meth)acrylate monomer unit to the entirety of the synthetic polymer film is not less than 15 mass % and less than 45 mass %.

Abstract: A synthetic polymer film is a synthetic polymer film whose surface has a plurality of raised or recessed portions. The synthetic polymer film has a crosslink structure, and the crosslink structure does not contain any nitrogen element that is a constituent of a urethane bond. The synthetic polymer film contains an organic carboxylic acid, and an amount of water required for dissolving 1 g of the organic carboxylic acid is equal to or greater than 10 mL and less than 10000 mL. At the lapse of 5 minutes since placing a 200 μL drop of water on the surface of the synthetic polymer film, a pH of an aqueous solution is not more than 5, and an area equivalent circle diameter of the aqueous solution is not less than 20 mm. A synthetic polymer film whose surface has a microbicidal activity can be produced using a photocurable resin composition which contains an organic carboxylic acid or a photoacid generator which generates the organic carboxylic acid.

Abstract: A manufacturing method of a mold, the mold having at its surface a plurality of recessed portions whose two-dimensional size is not less than 10 nm and less than 500 nm when viewed in a direction normal to the surface, the method comprising: (a) providing a mold base (10); (b) partially anodizing the aluminum alloy layer (18), thereby forming a porous alumina layer (14) which has a plurality of minute recessed portions (14p); (c) bringing the porous alumina layer into contact with an etching solution, thereby enlarging the plurality of minute recessed portions; (d) detecting a protrusion (210) formed at a surface of the porous alumina layer or the mold base; (e) determining whether or not a height of the detected protrusion is greater than a predetermined height; and (f) if it is determined at step (e) that the height of the protrusion is greater, irradiating the protrusion with laser light such that the height of the protrusion becomes smaller than the predetermined height.
