Patent number: 7182984Abstract: An ink jet-printing medium comprising a substrate and an ink-receptive layer which has at least one layer and is formed on at least one major surface of the substrate, in which at least one layer of the ink-receptive layer contains fibrous fine powder as a pigment in an amount of at least 20% by weight of the total weight of the whole pigment contained in the layer which contains the fibrous fine powder. This medium can be produced at a low cost and has high printing quality while suppressing the discoloration or fading of the prints.Type: GrantFiled: March 13, 2001Date of Patent: February 27, 2007Assignee: Hitachi Maxell, Ltd.Inventors: Kenji Kohno, Noriaki Ohtani

Patent number: 7172651Abstract: Pigment suitable for use in coating compositions for inkjet recording media. Surfaces of an inorganic particulate are interacted with a water-soluble polyvalent metal salt in an aqueous medium. The treated particle surfaces have a significant cationic surface charge imparted to them. The salt is a salt of a metal of Group II or Group III of the Periodic Table. Inkjet recording media treated with a coating composition containing the above pigment provide high density, fast-drying, and non-feathering ink images with suitable water fastness, while the coating compositions also offer cost advantages and improved rheology at higher pigment levels over coatings based on silica pigments.Type: GrantFiled: June 17, 2003Date of Patent: February 6, 2007Assignee: J.M. Huber CorporationInventors: Ching-Yih Chen, Ricky L. Giddens, Richard D. Carter

Patent number: 7087275Abstract: A coating fluid for application to a support to prepare an ink jet recording medium comprises an aqueous dispersion of a synthetic polymer hydrogel and gelatin, the amount of the synthetic polymer hydrogel being from 5 to 50% by weight of the combined weight of synthetic polymer and gelatin. Preferably the coating fluid also contains a mordant, an aliphatic alcohol to assist dispersion of the hydrogel polymer and a particulate material to impart a porous structure to the coating. The invention also provides an inkjet recording medium comprising a support on which is an ink-receiving layer comprising the gelatin and a synthetic polymer hydrogel. The amount of the latter may be from 0.3 to 5 g/square meter.Type: GrantFiled: May 30, 2002Date of Patent: August 8, 2006Assignee: Eastman Kodak CompanyInventors: Julie Baker, Malcolm D. Purbrick
