摘要：
An ink jet ink composition comprises a liquid vehicle, a pigment, and a polymer to overcome conductivity. The problem to be addressed for carbon black pigment inks is how to achieve high dried ink film resistivity while maintaining print quality. With the present invention, dried ink resistivity of aqueous pigment ink is improved by using polymers to overcome conductivity. The present invention results in significant improvement in dried film resistivity of carbon black pigment ink jet inks, sufficient to eliminate charge lead to charge lead shorts and improve machine runnability and can, therefore, be used in ink jet printers.
