Ink Components
The average ballpoint pen's ink is composed of dye or pigment particles – carbon black for black pens, eosin for red, or a suspected cocktail of Prussian blue, crystal violet and phthalocyanine blue for the classic blue pen – suspended in a solvent of oil or water.
There Are Million Of Formulas Of Making Pen Ink.There are many different colors of ballpoint pen ink, with black and blue probably being the most common.
Ink for a ballpoint pen gets its color from a pigment.
The pigment in black ink is carbon black, which can be made from coal or petrochemicals.
In blue ink, various pigments are used.
The blue colorant is usually an alkali dye based on triarylmethane.
Modern inks for pen and other uses are actually quite complex substances, composed of dyes, pigments, resins, solvents, lubricants, solubilisers, surfactants and even particulate matter, plus other chemicals.
For writing inks, the general need is for quick drying — otherwise it’ll take you practically forever to start writing the next page.
The major ballpoint pen makers such as Bic and PaperMate keep their ink formulas well-guarded — because the ballpoint pen market is such a big one globally.
Chemically speaking, ballpoint inks are even more complex.
Normally, they are a paste containing 25%–40% chemical dye (colorant) suspended in an oil or fatty acid that acts as the solvent to keep the ballpoint lubricated and clog-free.
