Thermal transfer ribbon with super high-temperature resistant transfer print marks and preparation method thereof

The invention belongs to the technical field of hot printing materials, and discloses a thermal transfer ribbon with super high-temperature resistant transfer print marks. The thermal transfer ribbonis composed of a base film, and a back coating and a thermal transfer printing layer which are smeared on the two sides of the base film separately, wherein the thermal transfer printing layer is divided into two parts; an ink layer and a surface coating are sequentially arranged on the surface of one side of the base film from inside to outside; and the ink layer is composed of the following rawmaterials by weight percent: 15% to 40% of polyester resin, 15% to 35% of petroleum resin, 5% to 15% of butadiene-styrene copolymers and 30% to 55% of silicon carbide. According to the thermal transfer ribbon, the ink layer and the surface coating are reasonably matched, particularly, the high-temperature resistant dye, silicon carbide, is utilized, the high temperature resistance effect of the transfer print marks is impr
