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 including: (a) providing a mold base, (b) partially anodizing an aluminum alloy layer, thereby forming a porous alumina layer which has a plurality of minute recessed portions; and (c) after step (b), bringing the porous alumina layer into contact with a first etching solution, thereby enlarging the plurality of minute recessed portions of the porous alumina layer. Step (a) of providing the mold base includes (a1) providing a metal base, (a2) forming an aluminum alloy layer on the metal base, and (a3) forming a surface protection layer on the aluminum alloy layer. Step (a2) and step (a3) are performed in a same chamber.

Abstract: The present invention provides a transparent film with an excellent anti-fog property. The transparent film of the present invention includes: a base film provided on a surface with projections formed at a pitch equal to or shorter than the wavelength of visible light; and hydrophilic fine particles each having a particle size in the range of 15% to 50% of the pitch of the projections, the hydrophilic fine particles being held in gaps between the projections while being in contact with the projections, the hydrophilic fine particles held in the gaps between the projections being separated by spaces from bottoms of the gaps, the spaces forming channels on the surface.

Abstract: A laminated film can be easily used by general users and can prevent entry of foreign substances and air bubbles between the attached surfaces even when the film is manually attached in a typical room environment in which foreign substances such as dust are floating. A film attachment method using such a laminated film is also disclosed. In an embodiment, the laminated film includes: a first surface protective film; a foreign-substance-removing adhesive layer; a foreign-substance-removing film; an integrating adhesive layer; a second surface protective film; a substrate-attaching adhesive layer; and a functional film, the substrate-attaching adhesive layer exhibiting a higher bond strength with the functional film than with the second surface protective film.
