Abstract
The invention is ink pigment grinding resins for waterbased printing inks which are produced by the amidation of maleated or fumarated rosin with a polyamine containing a primary amine group to produce the water soluble polyaminoamidoimide resin. The resulting rosin resin may be employed over a wide range of pH values to produce stable low or high viscosity grind bases.
