METHOD FOR MANUFACTURING EMBOSSED SHEET AND APPARATUS THEREFORE, METHOD FOR MANUFACTURING PATTERNED SHEET, AND PATTERNED SHEET

摘要

An embossed sheet, on which fine embossed patterns are regularly formed on a surface, is manufactured without any defects and with a high quality at a high line speed and at a high level of productivity. A method for manufacturing an embossed sheet, in which irregularities of a surface of an emboss roller is formed by transfer on a surface of a flexible strip-shaped sheet W. After coating a resin solution which is diluted with an organic solvent, the sheet on which a resin solution layer is formed on a surface is continuously run, the organic solvent contained in this resin solution layer is dried, the sheet after dried is wound around the emboss roller which is rotating, and irregularities of a surface of the emboss roller are transferred to the resin solution layer, and then the resin solution layer is cured, with the sheet being wound around the emboss roller.
