本発明の床用化粧シートは、基材シート上に、少なくとも表面保護層を有する床用化粧シートであって、前記基材シートが熱可塑性樹脂シートであり、前記表面保護層の表面自由エネルギーが27mJ/m2以上30mJ/m2未満であり、且つ、前記表面保護層のマルテンス硬さが70N/mm2以上であり、東工大式滑り試験機(O-Y・PSM)を用いて測定した、綿100%の靴下による前記表面保護層の滑り抵抗値(C.S.R値)が、0.3以上であることを特徴とする。上記特徴を有する床用化粧シートは、適度に拭き取り抵抗がなく、住宅施工時の汚れ(特に汚染物質の内の大半の割合を占める、取り難い石膏粉)が床用化粧シート表面に存在していても、当該汚れが取り易いことに加えて、皮脂汚れ等の油汚れも容易に拭き取ることができる。また、拭いただけでは取りきれない汚れを、スクレーパー等の工具を用いて除去した場合に、床用化粧シート表面に傷が付きにくい。言い換えれば、本発明の床用化粧シートは、多様な種類の汚れに対する易掃性に優れる。そのため、本発明の床用化粧シートは、床用として好適に使用することができる。
本発明の床用化粧シートは、基材シートを有する。
本発明の床用化粧シートは、絵柄模様層を有していてもよい。
透明性樹脂層と絵柄模様層との密着性を高めるため、絵柄模様層上に接着剤層を形成してもよい。接着剤層は、透明性接着剤層であることが好ましく、当該透明性接着剤層としては、無色透明、着色透明、半透明等のいずれも含む。
本発明の床用化粧シートは、透明性樹脂層を有していてもよい。
