HARD FLOOR MATERIAL
PROBLEM TO BE SOLVED: To provide a floor material that can form a floor surface hardly receiving the effect of the surface condition of the ground surface below a floor, and having more flatness and excellent in appearance, even if the surface of floor substrate has irregularities.SOLUTION: A floor material comprises a laminate that includes a lower layer being in contact with the ground surface below a floor, and an upper layer laminated on a part of the lower layer. A hard floor material satisfies the following conditions: (1) a planar shape of the upper layer and the lower layer is a rectangle, and there is a joint area where the upper layer is not laminated on the top face of lower layer; (2) the upper layer includes a rigid resin containing layer, and a recess amount on the top face of upper layer measured by JIS A1454 "recess testing B method (2016)" is less than 0.2 mm; and (3) the lower layer includes a soft resin containing layer as an undermost layer, and a recess amount on the undersurface of lower layer based on the above testing is 0.2 mm or more.SELECTED DRAWING: Figure 1
【課題】たとえ床下地の表面に凹凸があったとしてもその表面状態の影響を受けにくく、より平坦で外観にも優れた床面を形成できる床材を提供する。【解決手段】床下地面に接触する下層と、当該下層上の一部に積層されている上層とを含む積層体から構成される床材であって、（１）上層及び下層の平面形状が矩形であり、下層の上面において上層が積層されていない目地領域を有し、（２）上層は、硬質樹脂含有層を含み、かつ、上層の上面におけるＪＩＳ Ａ１４５４の「へこみ試験 Ｂ法（２０１６）」によるへこみ量が０．２ｍｍ未満であり、（３）下層は、軟質樹脂含有層を最下層として含み、かつ、下層の下面における上記試験によるへこみ量が０．２ｍｍ以上である、ことを特徴とする硬質床材に係る。【選択図】図１
