Further, in a case in which a drying temperature or drying time is increased to dry the ink of which the surface energy is increased, a curl of the tipping paper is increased.

  • the fragrance material remains included in the carrier material and is not expressed before moisture or saliva is spread from the smoker to the tipping paper or friction is transmitted to the tipping paper (for example, by the smoker gripping or rubbing the tipping paper), a problem in that a scent is lost over the storage period or a problem in that a fragrance is unnecessarily expressed while the smoker is just keeping the smoking article may be solved.

  • the binder that may be included in the fragrance carrier ink may be an acrylic and starch-based polymer that is soluble in ethanol. Since the binder that may be included in the fragrance carrier ink is included therein, the residual amount of the fragrance material, which is included in the fragrance carrier, in the tipping paper may be increased. That is, the fragrance material or fragrance carrier that may be lost over the storage period of the smoking article after the smoking article is produced may be better preserved in the tipping paper by the binder.

In this way, it is possible to address a problem in that a fragrance is excessively expressed before smoking due to breakage of the microcapsules and/or a problem in that the surface of the tipping paper is contaminated by the shells of the microcapsules and roughens, which may occur when the fragrance carrier ink contains an excessive amount of microcapsules.
  • the weight ratio of the binder with respect to the total weight of the fragrance carrier ink may be in a range of about 5% to 10%, and the weight ratio of the microcapsules with respect to the total weight of the fragrance carrier ink may be in a range of about 5% to 20%.

However, in the tipping paper of Comparative Example 2 on which the water-soluble fragrance carrier was printed, it was confirmed that the ink was not completely dried after the printing and drying processes. This is judged to be due to the surface energy of the ink having a high value of 72.4 mN/m, which is due to using water as the solvent for the ink when printing the water-soluble fragrance carrier. In Comparative Example 3 in which the drying speed was lowered to 10 m/min to completely dry the ink for which water was used as the solvent, the extent to which the ink is dried was good, but a curl of the tipping paper occurred at a high numerical value of about 12 mm.

In this way, it was confirmed that the detected vanillin and ethyl vanillin components may serve to mask a tobacco smell on fingers by coming in contact with the fingers. Meanwhile, from the results of analysis of Example 4 and Comparative Example 4, it can be confirmed that, while the contents of the fragrance material in the ink were the same, more vanillin and ethyl vanillin components were detected in the case in which fragrance carrier printing was performed by including the fragrance material in the carrier material (Example 4) as compared to the case in which fragrance printing was performed without including the fragrance material in a carrier (Comparative Example 4).
