Patent number: 8901245Abstract: Methods for forming rosin-derived cationic compounds are provided. The method can include attaching a cationic group to a conjugated diene on a hydrophenathrene-based ring of a resin acid (e.g., levopimaric acid, abietic acid, dehydroabietic acid, or a mixture thereof) to form a rosin-derived cationic compound. Attaching the cationic group to the conjugated diene on the hydrophenathrene-based ring of the resin acid can be achieved via a Diels-Alder reaction of a dienophile with the hydrophenathrene-based ring of the resin acid. Rosin-derived cationic compounds are also provided. The rosin-derived cationic compound can include a cationic group attached to a conjugated diene on a hydrophenathrene-based ring of a resin acid, wherein the rosin-derived cationic compound further comprises a carboxylic acid group.Type: GrantFiled: December 10, 2013Date of Patent: December 2, 2014Assignee: University of South CarolinaInventors: Chuanbing Tang, Jifu Wang, Alan W.

Patent number: 7910635Abstract: The specification describes a process for making gelled ink resins which exhibit improved properties such as lower viscosity under low shear and less viscosity decrease with increasing shear. In a preferred embodiment, a rosin-based or hydrocarbon-based resin is mixed with an organic solvent and reacted with a polyamine reactant, such as melamine-formaldehyde resin or hexamethylene diamine, 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.Type: GrantFiled: October 14, 2006Date of Patent: March 22, 2011Assignee: Lubrizol Advanced Materials, Inc.Inventors: John H.
