What important role does the acid and alkali resistance of pigments play in water-based ink applications?

What important role does the acid and alkali resistance of pigments play in water-based ink applications?

Most resins used in water-based inks are carboxylic acid type, which become water-soluble resin after neutralization with ammonia. Therefore, the water-based binder is acidic. If the pigment used in the water-based ink is acidic, it is possible to acidify the water-soluble resin, causing the resin to agglomerate and destroying the suspension structure of the ink. However, pigments that are too basic are likely to cause saponification of the resin; pigments with high water solubility will also destroy the stability of the binder, so the choice of pigments for water-based inks should consider its acidity, alkalinity, water solubility and other factors.
