Abstract
A process for producing a gelled ink vehicle for heatset printing including the sequential steps of first mixing a modified rosin ester and a liquid alkyd resin and a fatty acid ester solvent, reserving some of the solvent for later use, which is then heated and stirred until the modified rosin ester is dissolved. A gellant is optionally added, and the reaction mixture is maintained at temperature. A non-optional first gellant is then added to the reaction mixture. The reaction is allowed to progress, after which the balance of the solvent, which was withheld previously, is added. The vehicle is recovered from the reaction vessel. The process produces a vehicle that has a stronger gel structure than traditional ink vehicle gels.
