Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer material preparation, in particular to an adhesive for thermal sublimation transfer printing and a synthesis process thereof. Background technique [0002] Thermal transfer printing is a newly emerging special printing technology in recent years. Its principle is to directly contact the transfer printing film with the pattern on the substrate, and through the heating and pressure of the thermal transfer head and the impression cylinder, the ink on the transfer film The graphic layer is melted and transferred to the substrate. The most important material in thermal transfer printing technology is the transfer film, and the research and development of materials related to thermal transfer film such as carrier layer, release layer, protective layer, ink layer, and adhesive layer is still in its infancy. The coatings are closely related and affect each other. Among them, the bon...
