Abstract
Description
【発明の詳細な説明】 本発明はインキの改良に関するものである。[Detailed description of the invention] The present invention relates to improvements in inks.
従来、プリンターや筆記具等に用いられるインキは一般
的（＝ドライアップが避けられない欠点を有している。Conventionally, ink used for printers, writing instruments, etc. has the disadvantage that dry-up is unavoidable.

することはなかなか困難であった。In addition, dry-up can be avoided, but at the same time (-) a smooth writing flow rate can be obtained with a low load, and (-) it provides an ink with excellent writing properties that can withstand double-speed single-speed writing. It was quite difficult to do so.
本発明は斯る問題点を解決して長時間（約１ケ月）の使

である。The present invention solves these problems and allows for dry-up even after long-term use (approximately one month), smooth writing flow rate with low load, and high-speed writing (5 to 20 m/min). min
) As a result of intensive research to provide high-quality ink with followability that can withstand even low activity (100P5 at 20℃))
, below), has good solubility in dye (Toku 6 oil-soluble dye) C2, and JI! We found that the above problems could be solved by using a solvent that satisfies the following conditions: a slow evaporation rate, that is, an island boiling point, etc. After repeated tests and studies, we found that the viscosity was 1.380P (at 40℃). ), the boiling point is 24
The first method is to contain propylene carbonate, which has good solubility in dyes, as a solvent at 2.0°C.

ペン等の提供をも可能とするものである。As described above, the present invention is manufactured using a solvent containing propylene carbonate as a composition, so that dry-up gaskets can obtain smooth writing flow with low load, and can withstand high-speed writing. It exhibits an excellent effect that enables the provision of surface-quality ink with followability.
This makes it possible to make current printers, water-based ballpoint pens, water-based felt-tip pens, etc. non-dry, and it also makes it possible to provide low-viscosity oil-based ballpoint pens.
