PROBLEM TO BE SOLVED: To improve surface hardness, stain resistance, chemical resistance, and processability by a method in which an expandable resin layer is installed on a substrate, a printing layer is formed optionally, and an ultraviolet curable resin layer is laminated on a surface. SOLUTION: In a foamed embossed decorative sheet, an expandable resin layer 2 is laminated on a substrate 1 and adjusted not to be expanded by heating. Next, a printing layer is installed optionally using oil ink or water-color ink, and an ultraviolet curable resin layer 4 is laminated on a surface for constitution. The expandable resin layer 2 can be laminated on the substrate 1 by application using a knife coater, a gravure coater, etc. The ultraviolet curable resin layer 4 is laminated on the expandable resin layer 2 by a method similar to that in which the expandable resin layer 2 was laminated on the substrate 1. Drying is done in a similar method. The laminate, after being expanded by heating to a foaming temperature, is embossed by a embossing roll. The surface of the ultraviolet curable resin of the sheet is irradiated with ultraviolet rays to be cured completely. |
