Abstract: The present invention is to provide a photo-curable transfer sheet suitable for the preparation of an intermediate stamper in a nanoimprint method, in which the mold release properties from a mold having a fine concave-convex pattern used in the preparation of the intermediate stamper and the mold release properties of a cured photo-curable resin that is a product having a fine concave-convex pattern transferred from the intermediate stamper are excellent, and the transfer property of the fine concave-convex pattern is good; and a method for forming a concave-convex pattern by using the above-mentioned photo-curable transfer sheet. The photo-curable transfer sheet 10 having a photo-curable transfer layer 11 comprising a photo-curable composition deformable by application of pressure which comprises a polymer and a reactive diluent having a photopolymerizable functional group, wherein the polymer is an acrylic resin comprising a recurring unit derived from (meth)acrylate having an alicyclic group.

Abstract: The present invention is to provide a photo-curable transfer sheet suitable for the preparation of an intermediate stamper in a nanoimprint method, in which the peeling property from a mold having a fine concave-convex pattern used in the preparation of the intermediate stamper and the peeling property of a cured photo-curable resin that is a product having a fine concave-convex pattern transferred from the intermediate stamper are excellent, and the adhesion to a base film is good; and a method for forming a concave-convex pattern by using the above-mentioned photo-curable transfer sheet.

Abstract: The present invention provides a method for forming concave-convex pattern corresponding to a nanoimprint method which is advantageously utilized in the preparation of electronic devices, optical parts and recording media, and enabling the preparation of the product having the fine pattern mentioned above in cheapness and high speed.
