  • Decorative sheet and decorative material
    Patent number: 6761979
    Abstract: A decorative sheet using a paper substrate is provided which, even in the case of the adoption of a construction such that a surface resin layer has been formed by crosslinking through an ionizing radiation irradiation to improve surface properties such as abrasion resistance, does not cause an unfavorable phenomenon such that the workability is lowered due to a deterioration in strength of the paper substrate caused by the ionizing radiation and, consequently, the sheet is broken at the time of lamination. A decorative sheet S comprises, stacked in the following order from the top surface toward the back surface, a surface resin layer 4 formed of a crosslinked product of an ionizing radiation-curable resin, a paper substrate 1, and a high-modulus resin layer 2 having a tensile strength of not less than 40 MPa as measured according to JIS K 6301. A pattern layer 3 or the like may be additionally provided. The use of a needle-leaved tree pulp as the paper substrate is preferred from the viewpoint of strength.
