Abstract
Aqueous based printing ink compositions adapted for use in gravure and flexographic printing on hydrophobic substrates are prepared by combining a low-viscosity resin emulsion having an average particle diameter of less than about 0.5 microns and comprised of hydrophobic, moisture resistant, adherent resin forming components with a pigment paste containing a water-soluble polymer. The printing inks are substantially devoid of volatile organic solvent.
