Patent No. 200610098357.3 discloses a whiteboard pen ink, adding organic solvents, during the writing process, the organic solvents volatilize, causing pollution to the environment and harm to the human body
Most of the existing liquid inks use chemical synthetic pigments or dyes, and add organic solvents. Long-term use and contact with the human body will have adverse effects on the health of teachers; and there is generally a problem of poor storage stability. The active ingredients in the ink are easy to precipitate, resulting in poor writing. The color of the font is uneven, and even the pen head is blocked, which brings a lot of inconvenience to the teaching
