The invention discloses an ink, a preparation method thereof, and an application of the in thermochromic tipping paper for cigarette, and relates to the technical field of inks. The ink is composed ofa common ink and a thermochromic material, wherein the common ink mainly comprises an acrylate copolymer, a pigment, ethanol, water, a nano-microcapsule and an assistant, and the thermochromic material mainly comprises a thermochromic toner. The ink provided by the invention has a temperature sensing function, so the color of the ink on the surfaces of tobacco rods packaged with the tipping paperfor cigarette changes with the temperature of smoke in the smoking process in order to realize the color change of the tipping paper for cigarette, thereby the decoration effect of the tipping paperfor cigarette is improved, and the functionality and the practicality of the tipping paper for cigarette are enhanced; and the preparation method of the ink can effectively improve the preparation efficiency and quality of the ink, and the raw materials of the ink can be proportioned as required, so that the application of the ink in the tipping paper for cigarette can meet different demands.
