Abstract: A hot pressing membrane includes a carrier film, a decorative layer formed on the carrier film, and a transparent protective layer formed on the decorative layer. The decorative layer includes, in parts by weight, 4.0 to 6.0 parts by weight of a first thermoplastic polyurethane, 1.0 to 2.0 parts by weight of a pigment, and 12.0 to 15.0 parts by weight of a first solvent. The transparent protective layer includes, in parts by weight, 4.0 to 6.0 parts by weight of a second thermoplastic polyurethane, 0.6 to 2.0 parts by weight of a functional additive, and 11.0 to 14.0 parts by weight of a second solvent. The hot pressing membrane of the invention is via the carrier film bonded to an outer surface of an object by a hot pressing process. The hot pressing membrane of the invention has a scratch resistance equal to or greater than 50 times.
