DECORATIVE MATERIAL FOR FLOORING
PROBLEM TO BE SOLVED: To prevent distasteful rubbing sound from being generated by walking without damaging anti-slip performance, while inhibiting a warp and the like from being generated.SOLUTION: A decorative material for flooring 10 includes a decorative sheet 1 on one face of a woody base material 11 and a moisture-proof film 20 on the other face. The woody base material 11 has a dimensional variation per 1% water content change that is larger than 0.02% and has an average water content that is 6 to 10 mass%. The moisture-proof film 20 has a moisture permeability that is equal to or lower than 7 g/m24 hr. On a surface on the decorative sheet 1's side are formed a plurality of salients 5. Each salient 5's height is within a range equal to or larger than 20 μm and equal to or smaller than 80 μm. A circle obtained by converting area of each salient 5 in a plan view to a circular shape has a diameter within a range equal to or larger than 40 μm and equal to or smaller than 200 μm. The plurality of salients 5 are randomly arranged so that a rate of area, per unit area in a plan view, occupied by the plurality of salients 5 is within a range equal to or larger than 0.05 and equal to or smaller than 0.5.SELECTED DRAWING: Figure 1
【課題】反り等の発生を抑制すると共に、防滑性能を損なうことなく歩行に伴う不快な擦り音の発生を防止する。【解決手段】床用化粧材１０は、木質基材１１の一方の面に化粧シート１が他方の面に防湿フィルム２０が設けられている。木質基材１１は、１％含水率変化当たりの寸法変化量が０．０２％よりも大きく、且つ平均含水率が６〜１０質量％である。防湿フィルム２０は、透湿度が７ｇ／ｍ２・２４時間以下である。化粧シート１側の表面に複数の凸部５が形成され、凸部５の高さは２０μｍ以上８０μｍ以下の範囲であり、平面視における上記各凸部５は、その面積を円形状に換算した場合に円の直径が４０μｍ以上２００μｍ以下の範囲であり、平面視における単位面積当たりに上記複数の凸部５の占める割合が０．０５以上０．５以下の範囲で、当該複数の凸部５がランダムに配置されている。【選択図】図１
