PHOTOCURABLE TRANSFER SHEET, AND METHOD FOR FORMING RECESSED AND PROJECTED PATTERN USING SAME

摘要

Disclosed is a photocurable transfer sheet which can be advantageously used for the production of an intermediate stamper that is used in a nanoimprinting process. The photocurable transfer sheet exhibits excellent releasability from a mold, which is used for the production of the intermediate stamper and has a fine recessed and projected pattern, and also exhibits excellent releasability from a photocurable resin to which a recessed and projected pattern is transferred from the intermediate stamper. In addition, the photocurable transfer sheet exhibits excellent transferability of a recessed and projected pattern. Also disclosed is a method for forming a fine recessed and projected pattern using the photocurable transfer sheet. Specifically disclosed is a photocurable transfer sheet (10) which comprises a photocurable transfer layer (11) that can be deformed by the application of a pressure and is composed of a photocurable composition that contains a polymer and a reactive diluent agent. The photocurable transfer sheet (10) is characterized in that the polymer is composed of an acrylic resin that contains a (meth)acrylate repeating unit having an alicyclic group. Also specifically disclosed is a method for forming a recessed and projected pattern using the photocurable transfer sheet (10).
