Abstract
This invention provides a high-solids, low-viscosity, aqueous vehicle particularly adapted for use in coating cellulosic substrates under ambient conditions. The vehicle comprises a water-soluble oil with minute styrene polymer particles uniformly dispersed therein. The water-soluble oil portion comprises the reaction product of a dibasic acid or a dibasic anhydride and a drying oil which is then reacted to provide the water-soluble salt thereof with a nitrogen base. The aqueous vehicle is especially useful in high solids inks and overprint varnishes.
