。(Function) The reasons why the oil-based ink according to the present invention is stable over time (a) and does not cause blurring of handwriting are speculated as follows. In other words, ethylene glycol is relatively hydrophilic, and salt-forming oil-soluble dyes are also nearly hydrophilic, so they have strong affinity and are compatible with each other, and the salt-forming oil-soluble dye dissolves in the solvent over time. To improve stability,
The above-mentioned dye becomes insolubilized and does not precipitate over time.
