METHOD FOR PRODUCING EMBOSSED DECORATIVE SHEET FOR FLOOR
PROBLEM TO BE SOLVED: To provide a method for producing an embossed decorative sheet for floor which is excellent in caster resistance and impact resistance, and is excellent in reproducibility, weather resistance and flexibility of embossment.SOLUTION: There is provided a method for producing a decorative sheet 30 in which a pattern layer 20, an adhesive layer 21, a transparent thermoplastic resin layer and a surface protective layer 24 are layered in this order on a thermoplastic resin base material sheet 16, and an adhesive layer 17 and backer layers 18 and 19 are provided in this order on a rear face of the base material sheet, the backer layers 18 and 19 are formed by forming the adhesive layer 17 on a rear face of the base material sheet and then extrusion-laminating a plurality of layers 18 and 19 containing a molten thermoplastic resin, then the pattern layer 20 is formed on the surface of the base material sheet 16 by printing, the adhesive layer 17 is formed thereon, then the transparent thermoplastic resin layers 22 and 23 are formed by extrusion-molding a plurality of layers 22 and 23 containing the molten transparent thermoplastic resin, and embossment is performed.SELECTED DRAWING: Figure 5
【課題】耐キャスター性、耐衝撃性に優れ、かつエンボスの再現性、耐候性、柔軟性等に優れた床用エンボス化粧シートの製造方法の提供。【解決手段】熱可塑性樹脂基材シート１６上に、絵柄模様層２０、接着剤層２１、透明熱可塑性樹脂層、及び表面保護層２４がこの順に積層されており、且つ基材シートの裏面に接着剤層１７、バッカー層１８、１９がこの順に施されている化粧シートであって、バッカー層１８、１９は、基材シートの裏面に接着剤層１７を形成した後、溶融した熱可塑性樹脂を含んでなる複数層１８、１９を押し出して積層することによって形成し、その後に、基材シート１６の表面に印刷によって絵柄模様層２０を形成し、その上に接着剤層１７を形成した後、溶融した透明熱可塑性樹脂を含んでなる複数層２２、２３を押し出して積層することで、透明熱可塑性樹脂層２２、２３を形成し、エンボス加工を行う床用エンボス化粧シート３０の製造方法。【選択図】図５
