Abstract
The specification discloses an improved ink vehicle for lithographic ink formulations. The ink vehicle contains a high viscosity primary resin component and a co-resin which is an acid catalyzed rosin or modified rosin ester. As contrasted with an ink vehicle containing a base catalyzed rosin ester co-resin, vehicles containing the acid catalyzed rosin ester co-resin exhibit substantially lower water pick up rates which improve the emulsification properties of an ink formulation containing the vehicle. The specification also discloses a method for making an ink vehicle having improved water emulsification properties.
