  • the binder that may be included in the fragrance carrier ink may be an acrylic and starch-based polymer that is soluble in ethanol.
  • the binder When the binder is included in the fragrance carrier ink, 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.

  • the binder may be a polymer material that has a molecular weight in a range of about 3,000 to 20,000 and a glass transition temperature in a range of about 60° C. to 90° C. This is because, when the viscosity of the binder is too low, the ink may flow down, and when the viscosity of the binder is too high, the ink may become stiff, which may degrade the workability and performance of the binder itself.
  • a fragrance retaining property tends to increase with an increase in an amount of applied binder, but in a case in which too much binder is applied, the curl of the tipping paper may be increased, and there may be difficulty in producing the smoking article.

  • the fragrance may also have the same composition as the fragrance material included in the fragrance carrier material.
  • a content ratio of the PVA and the fragrance in each microcapsule may be in a range of about 1:3 to 1:7.
  • the content ratio of the PVA and the fragrance in each microcapsule is about 1:5.
  • each microcapsule may be produced by stirring about 5% PVA, about 25% fragrance, and about 1.5% cross-linking agent.

  • An OPV printing process was performed on a tipping paper material produced for testing of examples, which had undergone and completed a process of printing a first design and a process of printing a second design different from the first design, and then a drying process was performed at a drying speed of about 150 m/min.
  • a printing process using an ink including a water-soluble fragrance carrier including a fragrance material was performed on the tipping paper material of Comparative Example 1, which had undergone and completed the OPV printing process and the drying process, and then a drying process was performed at a drying speed of about 150 m/min.
  • a fragrance carrier ink for which water was used as a solvent and which contained about 1.25% fragrance material(s) of Table 1 above, about 9% ⁇ -cyclodextrin, and about 5% water-soluble binder, was used.

  • a fragrance carrier ink for which ethanol was used as a solvent and which contained about 1.25% fragrance material(s) of Table 1 above, about 9% 2-hydroxypropyl- ⁇ -cyclodextrin, and about 5% binder, was used.
  • Example 2 As shown in Table 2, the extent to which the fragrance carrier is dissolved was good in all of Example 1 and Comparative Examples 2 and 3. 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 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. Thus, the tipping paper of Comparative Example 3 was found to be not applicable to a cigarette mass production process.
  • a tipping paper was removed from a cigarette produced for testing, and a material portion and a filter portion were separated.
  • a smoking article was produced by combining the separated material portion and filter portion using a tipping paper having a porosity of about 100 CU that was produced by applying the OPV process and the fragrance carrier printing process using an ethanol-based fragrance carrier ink containing 0.4% fragrance material.

  • Example 4 vanillin and ethyl vanillin components were detected in all of the examples. Therefore, 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.
  • 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).
  • Example 5 in which the content of the fragrance material included in a carrier was 1.5%, a problem occurred in that a fragrance spread to other tipping paper, to which the fragrance should not be applied, in addition to being spread to the tipping paper of the present invention during a cigarette mass production process. It was found that, in Example 4 in which the content of the fragrance material included in a carrier was 1.25%, the effect of reducing a tobacco smell on fingers caused by smoking was excellent and the tipping paper could be applied to cigarette mass production without any problems.

However, in the case of Example 9 in which the content of the binder was 15%, there was a problem in that an excessive curl occurred in the tipping paper. It was found that, when the content of the binder was in a range of 5% to 10%, the effect of reducing a tobacco smell on fingers caused by smoking was excellent and the tipping paper curl issue could also be solved.
  • a smoking article was produced in the same way as in Example 8 described above with reference to Table 4, except that the ethanol-based fragrance carrier ink contained 5.0% microcapsules.
  • microcapsules each having a diameter in a range of about 1.5 ⁇ m to 5.0 ⁇ m were used, wherein a core of each microcapsule was an ethanol-based fragrance, a shell of each microcapsule was made of PVA, and Na 2 SO 4 was used as a cross-linking agent.

  • Example 8 the workability of printing on the tipping paper was good.
  • a problem of adhesion between front and rear surfaces of the tipping paper did not occur, which may occur when the paper is rolled while the ink is not completely dried and the ink on the front surface is spread to the rear surface.
  • the slip property was good without a problem in that the surface of the tipping paper was too slippery or rough, and a curl of the tipping paper was also within an appropriate numerical value range. Accordingly, it was confirmed that, according to the examples, there was no problem in terms of the workability of fragrance carrier printing using the fragrance carrier ink including the fragrance material, binder, and the microcapsules.
