Patent number: 5559206Abstract: The specification describes a process for making highly functionalized rosin ester resins; i.e., partially esterified rosin based resins. The resins are produced by reacting fortified rosin with a polyol at superatmospheric pressure in a closed reaction vessel while retaining at least a portion of the water formed during the esterification step in the reaction vessel, thereby limiting the reaction to a desired degree of partial esterification so that a relatively high degree of residual acid functionality is achieved in the final ester product. The process enables large scale production of resins with precise control of the degree of functionality of the resins thus produced. The products are particularly useful as binders in ink formulations.Type: GrantFiled: March 1, 1995Date of Patent: September 24, 1996Assignee: Arizona Chemical CompanyInventor: Theodore J. Williams

Patent number: 5427615Abstract: 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.Type: GrantFiled: August 20, 1993Date of Patent: June 27, 1995Assignee: Arizona Chemical CompanyInventor: Thomas C.
