Abstract
Description of an inkjet ink for application in inkjet printers, comprising (a) a solvent, which contains at least 80% of a homopolar, non-watery solvent, (c) one or several phospholipides. In such inkjet inks, the phospholipides have a stabilizing effect. In some applications it may be beneficial with respect to certain pigments to employ an additional dispersant. The inkjet ink has, with concurrent high dispersing stability, significantly improved de-wetting property, with high optical density and excellent storage stability on a nozzle plate of an inkjet print head.
