Abstract:
1. A sheet for manufacturing a concave-convex pattern comprising: a sheet-like member including a thermoplastic resin that is softenable by heating; a concave-convex pattern layer on one of the surfaces of the sheet-like member; and a reverse concave-convex pattern layer continuing over two or more concaves of the concave-convex pattern layer to mesh at least partially with the concave-convex pattern layer, wherein either one of the concave-convex pattern layer and the reverse concave-convex pattern layer includes metallic elements or metalloid element, wherein glass transition temperatures of the concave-convex pattern layer and the reverse concave-convex pattern layer are higher than a glass transition temperature of the sheet-like member, wherein the reverse concave-convex pattern layer is preformed to have the reverse concave-convex pattern such that convexes of the reverse concave-convex pattern layer fit to infill concaves of the concave-convex pattern block.
