DECORATIVE LAMINATE
PROBLEM TO BE SOLVED: To provide a decorative board unlikely to cause undesirable warping.SOLUTION: The decorative board of the present invention contains a melamine resin, and a surface layer of the decorative board has a relative dielectric constant of 1.8 or more and 6.5 or less. It is preferable that the surface layer is provided in contact with a portion containing the melamine resin. The thickness of the surface layer is preferably 0.5 μm or more and 40 μm or less. The specific water vapor permeability coefficient of the surface layer under an environment of 40°C and 90% RH is preferably 0.9 or less. It is preferable that the decorative board has a core layer composed of a flame retardant fiber sheet.SELECTED DRAWING: None
【課題】不本意な反りを生じにくい化粧板を提供すること。【解決手段】本発明の化粧板は、メラミン系樹脂を含むものであって、化粧板の表面層の比誘電率が１．８以上６．５以下であることを特徴とする。前記表面層は、前記メラミン系樹脂を含む部位と接触して設けられているのが好ましい。前記表面層の厚さは、０．５μｍ以上４０μｍ以下であるのが好ましい。４０℃、９０％ＲＨの環境下における前記表面層の比水蒸気透過係数は、０．９以下であるのが好ましい。化粧板は、難燃性の繊維シートで構成された芯材層を備えるものであるのが好ましい。【選択図】なし
