| description | The invention provides self-disappearing thermo-sensitive paper, which comprises a base paper layer, an environment-friendly heat sensitive layer and a protective layer, the formula of the environment-friendly heat sensitive layer comprises a color former, a pigment, a heat sensitive agent, an adhesive, a filler and a solvent, and the solvent is water, ethanol or isopropanol; and an antioxidant and an ultraviolet light absorber which play a stabilizing role are added. The preparation method of the self-disappearing thermo-sensitive paper comprises the following steps: uniformly dispersing the color former, the pigment, the heat sensitizer and the filler to obtain a crude mixture; adding an adhesive and a proper amount of solvent, and adjusting to proper viscosity to obtain a heat-sensitive mixture; all the components are fully and uniformly mixed by stirring; uniformly coating base paper with the heat-sensitive mixture through a coating machine to form a heat-sensitive layer, and drying and curing to obtain t |
