STRUCTURE HAVING SPECIFIC SURFACE SHAPE AND METHOD FOR MANUFACTURING SAID STRUCTURE

WIPO Patent Application WO/2012/157717

A1

The present invention addresses the problem of finding out conditions relating to not only the shape but also the physical property of the surface as conditions required for a structure having light reflection preventing performance, light transmission improving performance, and the like to provide a structure to which especially mechanical strength such as surface scratch resistance, stain resistance, and the like are imparted, and providing a material for forming such a specific structure. The problem is solved by a structure having projecting portions with a specific height or recessed portions with a specific depth at the surface, the projecting portions or the recessed portions being present at specific intervals in at least one direction. The structure is characterized in that the structure is formed by the polymerization of polymerizable composites containing a (meta)acrylate compound by light irradiation, electron beam irradiation and/or heating, the (meta)acrylate compound contains 53% or more polyethylene glycol di(meta)acrylate by mass with respect to the entire (meta)acrylate compound, and the storage elastic modulus of the structure is within a specific range.
