Abstract
Provided are overprint varnish (OPV) compositions containing high viscosity essentially non-aqueous dispersions that include acrylic core/shell polymer particles in a non-aqueous solvent such as mineral oil. Also provided are methods of coating a substrate with an OPV containing the non-aqueous dispersions to improve the properties of the OPV when used to coat a substrate, such as improved rub resistance, resistance to yellowing, and desirable gloss values.
