DECORATION SHEET AND DECORATION PLATE
To provide a decorative sheet having excellent abrasion resistance in which whitening generated on the surface is reduced by heating a decorative sheet after construction.SOLUTION: There is provided a decorative sheet which has at least an adhesive layer, a substrate sheet and a surface protective layer in this order, wherein (1) the surface protective layer contains a curable resin and an inorganic filler, (2) the inorganic filler is spherical alumina and other spherical inorganic fillers other than alumina and (3) the particle diameter of the inorganic fillers of 90% or more of the particle diameters of the arbitrary 100 inorganic fillers, measured by observing a cross section obtained by cutting the decorative sheet in the direction parallel to a normal line on the surface of the decorative sheet, is 1 μm or more and less than 10 μm.SELECTED DRAWING: None
【課題】本発明は、耐擦傷性に優れ、且つ、表面に生じた白化が、施工後に化粧シートを加熱することにより減少する化粧シートを提供する。【解決手段】少なくとも、粘着剤層、基材シート、及び表面保護層をこの順に有する化粧シートであって、（１）前記表面保護層は、硬化型樹脂及び無機フィラーを含有し、（２）前記無機フィラーは、球状のアルミナ、及び、アルミナ以外の球状の他の無機フィラーであり、（３）前記化粧シートを、当該化粧シートの表面の法線と平行方向に切断した断面を観察して測定される、任意の１００個の前記無機フィラーの粒子径のうち９０％以上の前記無機フィラーの粒子径が、１μｍ以上１０μｍ未満である、ことを特徴とする化粧シート。【選択図】なし
