The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.Type: GrantFiled: January 14, 2005Date of Patent: April 6, 2010Assignee: Xerox CorporationInventors: Jennifer L.
