Zusammenfassung: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.
