Abstract
An ink jet ink composition comprises a liquid vehicle and a chemically modified pigment dispersion incorporating a chemical with a plurality of electron donating groups. The chemical is a monomer or a polymer. Dried ink film resistivity of aqueous carbon black pigment ink formulated in accordance with this composition is improved by being increased to a level whereby no electrical shorts which cause printer failure or print defects are observed during printing.
