Abstract
Provided are high viscosity essentially non-aqueous dispersions containing acrylic core/shell polymer particles in a non-aqueous solvent; sheetfed, heatset and coldset lithographic ink compositions containing the dispersions; and methods of printing with ink containing the dispersions to improve the setting and drying properties and rub resistance of sheet fed offset, heatset and coldset lithographic inks. The lithographic inks containing the dispersions set quickly enough to allow processing of printed sheets soon after printing.
