Abstract
Described herein is a polar non-aqueous dispersion comprising polar polymeric microparticles in a polar non-aqueous medium, the polar polymeric microparticles being insoluble in the medium and being produced by dispersion polymerization of vinyl monomers such as acrylate monomers in the medium in the presence of a polymeric acrylic stabilizer. Inks, coatings and overprint varnishes are formulated that employ the polar non-aqueous dispersion. Such inks, etc., exhibit superior chemical resistance properties, for example in one-part and two-part systems.
