TRANSPARENT FILM HAVING MICRO-CONVEXOCONCAVE STRUCTURE ON SURFACE THEREOF, METHOD FOR PRODUCING SAME, AND SUBSTRATE FILM USED IN PRODUCTION OF TRANSPARENT FILM

WIPO Patent Application WO/2013/035839

A1

The present invention pertains to a transparent film in which: a hardened layer, which has a micro-convexoconcave structure in which the average wave period of the convex or concave sections is 20-400nm, inclusive, is formed on the rough surface of a substrate film obtained from an acrylic resin having a rough surface in which the maximum valley depth (Pv) is 0.1-3μm, and the average length (RSm) of a contour curve element is 10μm; and the number of lattice squares in the hardened layer adhered to the substrate film is 51 or more when a cross cut test is performed using a 100-square lattice at 2mm intervals, in compliance with the JIS K 5400.
