Abstract
The present invention relates to a flooring material formed by sequentially accumulating a surface layer film, a printing layer and a back layer sheet. The surface layer film includes a thermoplastic polyurethane resin (A) having a Shore hardness of 40-80 D, a softening point of 100-150° C., and a light transmittance of greater than or equal to 90%. The back layer sheet includes a thermoplastic polyurethane resin (B) having a Shore hardness of 40-80 D and a softening point of 100-150° C.
