PROCESS FOR MAKING SELF-GELLED RESIN SOLUTION FOR INK FORMULATIONS

摘要

The specification describes a process for making gelled ink resins which exhibit improved properties. In a preferred embodiment, a rosin-based or hydrocarbon-based resin is mixed with an organic solvent and reacted with a cross-link agent under conditions sufficient to produce a substantially covalently cross-link gelled resin. The resulting gelled resin resists viscosity breakdown under high shear conditions and may be used directly for making ink compositions, obviating the need for further gelation and avoiding the use of conventional organo-metallic gelling agents.
