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.
