  • Patent number: 10792887
    Abstract: Provided is a decorative sheet that, due to an asperity profile, creates a highly textured impression, such as a contoured impression, three-dimensional impression, impression of depth, and the like, even after being molded, and that has exceptional surface flatness. This decorative sheet has a layer that includes at least a transparent resin film layer, the layer that includes at least the transparent resin film layer having on one surface thereof an asperity profile having recesses that reach the transparent resin film layer, and includes an area in which the depth (d) of the recesses of the asperity profile, and the thickness T from the start point of the depth (d) to the surface on the opposite side from the surface that has the asperity profile in the layer that includes the transparent resin film layer, satisfy the relationship (d)/T×100=5-10, and is intended for use as a decorative resin molded article in which a molding resin is laminated to the surface having the asperity profile.

  • Patent number: 10654245
    Abstract: The purpose of the present invention is to provide a decorative sheet having a bulging section on the surface thereof, wherein the bulging section is effectively inhibited from cracking during molding, and the decorative sheet is imparted with exceptional scratch resistance and quality of design in the convex/concave features on the bulging section after molding. The present invention pertains to a decorative sheet having a bulging section formed by a cured product of an ionizing-radiation-curable resin composition on a substrate sheet, the cured product of the ionizing-radiation-curable resin composition having a Martens hardness in a range of 10-120 N/mm2 at a temperature of 25° C. and a relative humidity of 50%.
