Abstract: A decorative sheet, a method for producing the same, and a decorative material are provided. The method for producing a decorative sheet includes the steps of: forming a pattern layer on one surface of a thermoplastic resin substrate layer; forming a transparent thermoplastic resin layer on the pattern layer; and forming one or more surface protective layers on the transparent thermoplastic resin layer, wherein the step of forming the surface protective layer is a step of forming the surface protective layer by application of a coating liquid containing UV-curable resin and subsequent irradiation with 365 nm wavelength UV light with an integrated light quantity in a range of 100 mJ/cm2 or more and less than 400 mJ/cm2, and an overall thickness is in a range of 40 μm or more and less than 500 μm.

Abstract: A decorative sheet that includes at least a thermoplastic resin substrate layer, a transparent thermoplastic resin layer and a surface protective layer in this order. The surface protective layer is formed by laminating at least two layers. At least a second surface protective layer, which constitutes an outermost layer that is a layer located furthest from the transparent thermoplastic resin layer among layers constituting the surface protective layer contains an ionizing radiation-curable resin containing a multifunctional hexamethylene diisocyanate oligomer at a weight ratio of 60% or more. The arithmetic mean height of a profile curve measured from the second surface protective layer in accordance with JIS B 0601 is 15 μm or more, and the maximum height of the profile curve is 38 μm or more.
