PROBLEM TO BE SOLVED: To provide a decorative material for flooring having weather-proofness while inhibiting occurrence of a warp or drawn bending based on a moisture atmosphere even when using, as a woody base material, a woody base material having a dimensional variation per 1% water content change, the dimensional variation being larger than 0.02%.SOLUTION: A decorative material for flooring 10 includes a decorative sheet 3 provided on one face of a woody base material 1 and a moisture-proof film 2 on the other face. The woody base material 1 has a dimensional variation per 1% water content change that is larger than 0.02% and has an average water content that is within a range of 6 to 10 mass%. The moisture-proof film 2 has a moisture permeability that is equal to or lower than 1.0 g/m24 hr. The decorative sheet 3 includes a thermoplastic resin base material 3A made from olefin-based resin and a printed layer 3B and a surface protective layer 3E on the thermoplastic resin base material 3A's surface that are provided in this order. The surface protective layer 3E is made from resin containing an ultraviolet absorber and a thickness corresponding to a solid content application quantity equal to or larger than 5 g/mand equal to or smaller than 10 g/m.SELECTED DRAWING: Figure 1
【課題】木質基材として１％含水率変化当たりの寸法変化量が０．０２％よりも大きい木質基材を使用しても、湿度雰囲気に基づく反りや曳き曲がりの発生を抑制すると共に、耐候性を有する床用化粧材を提供する。【解決手段】床用化粧材１０は、木質基材１の一方の面に化粧シート３が設けられ他方の面に防湿フィルム２が設けられる。木質基材１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％の範囲である。防湿フィルム２は、透湿度が１．０ｇ／ｍ２・２４時間以下である。化粧シート３は、オレフィン系樹脂製の熱可塑性樹脂基材３Ａと、熱可塑性樹脂基材３Ａの表面に、印刷層３Ｂと表面保護層３Ｅとがこの順に設けられ、表面保護層３Ｅは紫外線吸収剤を含有した樹脂からなると共に厚さが固形分塗布量で５ｇ／ｍ２以上１０ｇ／ｍ２以下である。【選択図】図１
