ARTICLE HAVING FINE UNEVEN STRUCTURE ON SURFACE, AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2016/190247

A1

The purpose of the present invention is to provide a method that makes it easy to produce an article which has on a surface thereof a fine uneven structure and which is superior in abrasion resistance. Provided is a method for producing an article having on a surface thereof a resin pattern 28 (fine uneven structure) that has a plurality of regular projections 22 and bridge sections 26 that each form a link between adjacent projections 22 so as to demarcate bottom sections 24 formed between the projections 22. The method comprises: (a) a step for irradiating a photosensitive resin layer of a substrate equipped with the photosensitive resin layer with light from a light radiating means, via a photomask having a regular dot pattern; and (b) a step for developing the substrate equipped with the photosensitive resin layer, thereby obtaining an article having a resin pattern 28 (fine uneven structure) on a surface thereof. The photomask makes use of the Talbot effect, and the light from the light radiating means has a spread angle in one direction that is broader than a spread angle in another direction.
