Title:

METHOD FOR PRODUCING ARTICLE HAVING FINE SURFACE IRREGULARITIES

Document Type and Number:

WIPO Patent Application WO/2011/155480

Kind Code:

A1

Abstract:

Provided is a method for producing an article having fine surface irregularities, with which it is possible to maintain releasability between a mold and a cured resin layer even with repeated transfer of the fine irregularities of the mold, and, by means of performing relatively few transfers, to sufficiently minimize contamination of the surface of the article due to migration of the external release agent. The method for producing an article having fine surface irregularities comprises: a step (I) for treating the surface of a roll-shaped mold (20) having fine surface irregularities using an external mold release agent that comprises fluorine but does not comprise functional groups (B) capable of reacting with functional groups (A) present at the surface of the roll-shaped mold (20); and a step (II), carried out after step (I), for interposing an active energy ray-curable resin composition (38) comprising an internal release agent between the roll-shaped mold (20) and a film (42) (substrate), and irradiating an active energy ray onto the product in order to cure the resin and form a cured resin layer (44), to which the fine irregularities have been transferred, on the surface of the film (42) and thereby obtain an article (40) having fine surface irregularities.
