VATTENHALTIG POLYMERDISPERSION, SERSKILT FOR ANVENDNING SOM BERARE FOR TRYCKNINGSKOMPOSITIONER, SAMT FORFARANDE FOR DESS FRAMSTELLNING

摘要

The 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 dibasic anhydride and a drying oil which is neutralized with a nitrogen base. The aqueous vehicle is especially useful in high solids, ink formulations having a high pigment to binder ratio.
