  • Publication number: 20240316593
    Abstract: A decorative sheet includes a primary film layer and a surface protection layer provided on one surface of the primary film layer. The surface protection layer has, in its surface, a ridged portion protruding in a ridged pattern to form an irregular shape. The irregular shape of the surface protection layer has RSm/Ra within the range of 10 or greater and 300 or smaller. The surface protection layer includes an ionizing radiation-curable resin as a main material. The ionizing radiation-curable resin is a trifunctional acrylic resin with the main component having a repeating structure. The repeating structure is any of an ethylene oxide structure, a propylene oxide structure, and an ?-caprolactone structure. The single-bonded carbon ratio in the main component of the ionizing radiation-curable resin falls within the range of 0.725 or greater and 0.955 or smaller.
