Abstract: Disclosed is a process for the production of a fine structure through nanoimprinting a photocurable resin composition. The process includes the steps of (1) forming a photocurable resin composition for nanoimprint into a film on a support and transferring a pattern to the film by pressing the film with a nanostamper at a pressure of 5 to 100 MPa, in which the photocurable resin composition contains a curable compound component including at least one cationically polymerizable compound and/or at least one free-radically polymerizable compound; and (2) curing the patterned film to obtain the fine structure.
