It is a calligraphy ink smell ink composition obtained by adding borneol to a black ink containing bon black. The carbon black used in the present invention may be any brand name conventionally used in the production of inks. Examples of black inks include lithographic printing ink, gravure ink, letterpress printing ink, and screen printing ink. Various inks such as a printing ink and an ink for ink jet are exemplified. The particle size of the carbon black used at this time varies depending on the type of ink, but may be any conventionally used carbon black.

For example, the carbon black used in the offset ink has a particle size of about 10 to 70 nm in a powdery or granular form, and its physicochemical properties such as oil absorption, specific surface area, and volatile matter are determined by the blackness and gloss of the offset ink. , Toner, particle size, tack, flow characteristics, and printability. At this time, as a means for increasing the degree of blackness, a pigment such as an alkali bluener or a cyanine blue may be further added. Further, the carbon black used in the ink for ink jet may have a particle size of a size generally used conventionally. In the case of the aqueous type, an aqueous carbon black dispersion for inkjet supplied from a carbon black manufacturer may be used.

[0007] Borneol used in the present invention is a substance of CAS No. 507-70-0 obtained by hydrogenating camphor as shown in the following chemical formula 1. In addition, as a natural product, it is collected from a dragon tree. Borneol used in the present invention may be a mixture containing this as a main component. Borneol may be added in an amount of 0.01 to 20 parts by weight based on 100 parts by weight of the black ink containing carbon black. At this time, if the addition amount is 0.01 part by weight or less, no fragrance is exhibited, and if it is more than 20 parts by weight, elegant fragrance is lost, which is not preferable. The calligraphy ink smell ink of the present invention has the same aroma as solid ink by adding borneol.
