Patent number: 8377522Abstract: An inkjet receiver is described which comprises a support and one or more layer coated thereon, at least one layer of which comprises one or more metal organosilicate polymer particulate materials. The metal organosilicate polymer particulate materials are obtainable by contacting a metal salt with a silicon-containing compound having an organic substituent in an organic solvent, wherein either the silicon-containing compound contains a basic group and/or the reaction is conducted in the presence of a base, wherein the metal is selected from one or more of aluminum, magnesium strontium, calcium or zinc and the silicon-containing compound comprises hydrolyzable and non-hydrolyzable substituents such as to form a metal organosilicate polymer particulate material therefrom. The described inkjet receiver is useful for forming images by inkjet printing having excellent color fastness over time.Type: GrantFiled: December 19, 2007Date of Patent: February 19, 2013Assignee: Eastman Kodak CompanyInventors: Stephanie V.

Patent number: 8062719Abstract: The present invention relates to a material intended for forming or printing images, comprising a support and at least one hydrophilic binder-based layer, and its manufacturing method, said method enabling the gelation process of the hydrophilic binder to be controlled. The material according to the invention is characterized in that in at least one of said hydrophilic binder-based layers, said hydrophilic binder is gelated by complexation with a complexing agent present on a heat-sensitive polymer or copolymer, that is hydrophobic at temperatures higher than its lower critical solution temperature LCST to protect the complexing agent, and water-soluble at temperatures less than its LCST to make the complexing agent accessible, the LCST of the heat-sensitive (co)polymer being higher than the setting temperature of said hydrophilic binder. The material according to the invention can be used as photographic material or as material taking aqueous ink compositions applied by the inkjet printing technique.Type: GrantFiled: June 13, 2007Date of Patent: November 22, 2011Assignee: Eastman Kodak CompanyInventors: Olivier J.
