Patent number: 7384463Abstract: Phase change ink comprising an ink vehicle that includes at least one amphiphilic molecule. The amphiphilic molecule is capable of co-crystallizing into the at least one wax monomer to form functionalized spherulites which are then capable of hydrogen bonding to other similarly functionalized spherulites to form a bonded network of spherulites. Increased adhesive and cohesive strength of the ink on paper can result, thereby generating a robust image.Type: GrantFiled: October 30, 2006Date of Patent: June 10, 2008Assignee: Xerox CorporationInventors: Tyler B. Norsten, Peter G. Odell
