PROBLEM TO BE SOLVED: To provide a decorative material for a floor which has excellent impact resistance even in the case using a wood substrate having a specific gravity of 0.55 or less, and exhibits excellent crack resistance and dimensional stability of the wood substrate after temperature change due to hot and cold.SOLUTION: In a decorative material for a floor where a synthetic resin layer and a decorative sheet are laminated on a wood substrate having a specific gravity of 0.55 g/cmor less in this order, (1) the synthetic resin layer contains a thermoplastic resin A and a thermoplastic resin B, (2) the glass transition temperature of the thermoplastic resin B is higher than that of the thermoplastic resin A, (3) the content of the thermoplastic resin B is 10-50 pts.mass based on 100 pts.mass of the thermoplastic resin A, and (4) the thickness of the synthetic resin layer is 450-650 μm. |
