First, shellac is dissolved in an alcohol-based organic solvent to obtain a vehicle, which is further added with a dye, a pigment, and the like.When manufacturing this printing ink, shellac is dissolved in an alcohol-based organic solvent. The vehicle has been aged moderately.

印刷インクが望まれる。When this printing ink vehicle is used without aging, drying is fast and transfer of printing ink from a gravure roller to a rubber transfer roller and further transfer from the transfer roller to a printed material are insufficient on a printing press. And a good printed matter cannot be obtained. In addition, the gravure roller and the transfer roller are easily stained, and it is necessary to frequently stop the operation of the printing press to perform the cleaning operation. On the other hand, excessive aging makes it difficult to dry, so that printed characters and marks are blurred or transferred to other portions, so that good printed matter cannot be obtained. Since these problems depend on the appropriate maturity of the vehicle, stable quality printing inks are desired.
【０００４】このような印刷インクの熟成方法として

が印刷機材を腐食させるという問題もある。To solve this problem, Japanese Patent Publication No. 51-15768 proposes a method of accelerating ripening by adding sulfuric acid to a printing ink vehicle. Takes weeks. Also,
Since this method uses sulfuric acid, there is also a problem that the acid remaining in the ink corrodes printing equipment.

As a result of intensive studies to respond to the above-mentioned demands, when aging a printing ink vehicle for oral products obtained by dissolving shellac in an alcoholic organic solvent and esterifying shellac, aging is performed in the presence of a cation exchange resin. By doing
The ripening period is remarkably shortened, and as described above, the aging period, which is required for natural aging for more than 20 days and the addition of sulfuric acid for about one week, can be reduced to only about 5 to 7 hours. It has been found that a printing ink that is stable in quality can be prepared. In this case, it was also found that a similar effect can be obtained by aging in the presence of a cation-exchange resin with respect to a prepared ink in which a required additive as a printing ink such as a dye or a pigment is added to the vehicle.

をなすに至ったものである。The printing ink obtained by the aging method using the cation exchange resin has the same adhesiveness and peeling resistance as those of the printing ink obtained by the conventional natural standing method and the sulfuric acid addition method. It is superior in print quality to these conventional printing inks, enables good printing, has excellent workability at the time of printing, and can easily wipe off and remove dirt on print rolls. The present invention has been found to be highly industrial without the possibility of corrosion and has led to the present invention.

A method for producing a printing ink for an oral product according to the present invention comprises a printing ink vehicle obtained by dissolving shellac in an alcoholic organic solvent, or adding a pigment, a pigment, and the like to the vehicle. The aging of the printing ink containing the components is carried out in the presence of a cation exchange resin.

In the present invention, a cation exchange resin is used. The cation exchange resin is not particularly limited, but is preferably a strongly acidic type, and as a commercially available product, for example, Amberlyst 15, XN-1004, XN-1 manufactured by Organo Corporation.
For example, those used as acid catalysts in non-polar, water-insoluble chemical reactions such as 005 can be used.

を採用することもできる。As a method of aging using a cation exchange resin, a method of adding a cation exchange resin to a printing ink vehicle and stirring the mixture is preferably employed. In this case, the cation exchange resin is preferably added in an amount of 25 to 45% by weight based on shellac. If the amount of the cation exchange resin is less than 25%, it may take a considerable time for sufficient aging, and even if it exceeds 45%, there is not much difference in the aging effect. The aging time is usually preferably 3 to 10 hours, particularly preferably 5 to 7 hours. The aging can be usually performed at a temperature of 20 to 30 ° C., and room temperature is generally sufficient. After aging, the cation exchange resin can be removed by means such as filtration. Instead of adding and stirring the cation exchange resin, a method of passing the ink through a column filled with the cation exchange resin can also be adopted.

These components dissolve shellac in an alcoholic organic solvent. The printing ink may be mixed together at this time or after dissolution to produce a printing ink, and the printing ink may be subjected to an aging treatment. The aging method and conditions in this case are the same as above.
