DECORATIVE SHEET AND DECORATIVE PANEL
The present invention provides a decorative sheet having excellent anti-slip properties, anti-slip durability, impact resistance, and stain resistance, and also having excellent designability. The present 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 such 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.
