摘要： A decorative sheet having a surface-protecting layer, the surface-protecting layer having excellent contamination resistance, alkali resistance, etc., for a long period of time, while limiting the occurrence of breakage and cracks when an impact is applied thereto or during processing; and a decorative plate using the decorative sheet is provided. Specifically, a decorative sheet comprising a laminate, the laminate comprising at least a base material sheet and a first surface-protecting layer in sequence in the thickness direction; (1) the first surface-protecting layer comprising an ionizing radiation-curable resin containing two kinds of aliphatic urethane acrylates, i.e., resin A and resin B, wherein resin A is an aliphatic urethane acrylate with an isocyanurate skeleton, and resin B is an aliphatic urethane acrylate with an alicyclic skeleton without an isocyanurate skeleton, and (2) the first surface-protecting layer having a nanoindentation hardness of 160 MPa or more and 240 MPa or less.

摘要： The invention provides a decorative sheet having a surface-protecting layer on its outermost surface, (1) the surface-protecting layer having a Martens hardness of 30 to 170 N/mm2, the Martens hardness being a value measured in a manner that when the surface-protecting layer contains fine particles, a diamond indenter is pressed into a position avoiding the fine particles to measure the Martens hardness of a cross-section, (2) the surface-protecting layer having irregularities, the irregularities having an embossed shape with a pebbly pattern, a wood-grain pattern, a wooden pattern, a marble grain pattern, or a leather pattern, and the irregularities having an average interval Sm of 180 μm to 950 μm, (3) the surface-protecting layer having a maximum height Rz of 10 to 45 μm, and (4) the surface-protecting layer having a ratio of the area of a portion from the surface to a depth of 30 μm of 40% or more.
