Patent number: 6899487Abstract: An ink composition for oil-based ballpoint pens is comprised of a solvent, a colorant and an anti-corrosive wetting agent. The solvent is a water containing water-in-oil-type organic solvent. The colorant is a combination of a dye and a pigment, wherein the pigment is dispersed in the ink with a nonionic surfactant. The anti-corrosive wetting agent is a phosphate based surfactant. An oil-based ballpoint pen using the above ink is also included.Type: GrantFiled: September 24, 2003Date of Patent: May 31, 2005Assignee: Kabushiki Kaisha Pilot CorporationInventor: Takeshi Fujii

Patent number: 6863719Abstract: An ink composition comprising: a self-dispersing carbon black, a binder, a stabilizing dye comprising at least as many groups comprising CO2H or COSH as groups comprising SO3H, and an aqueous vehicle. The stabilizing dye can improve the reliability and performance of the ink composition. The addition of the stabilizing dye can reduce or prevent the formation of material that blocks the printhead vias and throats as a result of the presence of a binder in the ink. The ink composition can reduce the amount of maintenance needed to retain all of a printhead's nozzles through the life of the printhead.Type: GrantFiled: December 30, 2002Date of Patent: March 8, 2005Assignee: Lexmark International, Inc.Inventors: Susan H.
