Patent number: 7553883Abstract: The invention provides an aqueous pigment ink composition that ensures excellent recording characteristics on any type of recording mediums. An aqueous pigment ink composition of the invention includes a pigment, a water-dispersible polymer, water, and a water-soluble organic solvent, where the pigment is dispersed as primary particles having an average primary particle diameter of not greater than 50 nm and as secondary particles having a ratio of an average secondary particle diameter to the average primary particle diameter in a range of 1 to 10, and the water-dispersible polymer has a minimum glass transition temperature of lower than 100° C. Using this polymer ensures good dispersion stability and favorable glossiness on a glossy medium.Type: GrantFiled: May 16, 2005Date of Patent: June 30, 2009Assignee: Seiko Epson CorporationInventor: Masahiro Yatake

Patent number: 7550518Abstract: A three-dimensional printing materials system and method can produce both appearance models and small numbers of functional parts in an office environment. The method can include building cross-sectional portions of a three-dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas can be built by using an ink-jet printhead to deliver an aqueous solvent or binder to an adhesive particulate mixture, causing the particles of the mixture to adhere together, and to previous cross-sectional areas. The binder can include at least one of nonaqueous organic monomeric compound, anionically ionizable polymer, cationic polymer, polymer, waterborne colloid, or inorganic solute.Type: GrantFiled: February 28, 2005Date of Patent: June 23, 2009Assignee: Z CorporationInventors: James F.
