NATURAL OIL DERIVED GELLED INK VEHICLES

摘要

Novel natural oil derived ink vehicles are provided by a two step process that does not require the addition of gelants or the irreversible heat bodying or polymerization of the oil. The gelled natural oil may be used as the vehicle/carrier in the ink formulation or alternatively used as a carrier or dispersant for additives in ink formulations. The gelled ink vehicles disclosed have many advantages over ink vehicles disclosed in the prior art.
