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.

Publication number: 20110041715Abstract: A flexographic printing composition which comprises a carrier-swellable particle composition, such as a microgel particle composition, has improved printing performance and printing resolution, especially where the flexographic printing composition is an aqueous printing composition and the carrier is water. The composition is particularly beneficial for flexographic printing of such an aqueous printing ink onto low-energy surface substrates or impermeable substrates, in which the ink has improved adhesion, even in the absence of corona discharge treatment. The use of surfactant in an amount of at least 0.5% by weight of the ink composition enhances printed density and/or reduces mottling in solid printed areas.Type: ApplicationFiled: August 9, 2010Publication date: February 24, 2011Inventors: Christopher L.
