Abstract
The specification discloses a process for making high viscosity gelled ink resins which exhibit improved properties. In a preferred embodiment, a precursor resin is conducted through an extruder with a cross-linking agent, preferably a heat reactive phenolic resin, to induce formation of covalent cross-link bonds in the resin producing a high viscosity resin which resists viscosity breakdown under high shear conditions. The resulting gelled ink resins may be used directly in making ink, obviating the need for further gelation and avoiding the use of conventional organo-metallic gelling agents.
