Patent number: 8257907Abstract: Negative-working imageable elements have an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of the free radically polymerizable component upon exposure to imaging radiation, a radiation absorbing compound, one or more polymeric binders, and at least 5 weight % of core-shell particles comprising a hydrophobic polymeric core and a hydrophilic polymeric shell that is covalently bound to the polymeric core. The hydrophilic polymeric shell has one or more zwitterionic functional groups. These elements can be imaged such as by IR lasers to provide lithographic printing plates.Type: GrantFiled: June 12, 2009Date of Patent: September 4, 2012Assignee: Eastman Kodak CompanyInventors: Ting Tao, Eric E.

Patent number: 8084182Abstract: A negative-working imageable element has an imageable layer that includes an infrared radiation absorbing dye that upon exposure to thermal irradiation, changes from colorless to a visible color or from one visible color to another visible color, providing a ?E of at least 5 between the exposed and non-exposed regions of the imageable layer within 3 hours of its exposure to 300 mJ/cm2 at a laser power of 15 Watts. The imageable element can be imaged to provide images with improved contrast for print-out. The imageable layer includes a primary polymeric binder that has a backbone to which are attached pendant poly(alkylene oxide) side chains, cyano groups, or both, and is optionally present in the form of discrete particles.Type: GrantFiled: April 29, 2008Date of Patent: December 27, 2011Assignee: Eastman Kodak CompanyInventors: Heidi M.

Patent number: 7247418Abstract: Both single-layer and multilayer imageable elements have a substrate and at least one imageable layer. The elements can be used to prepare either negative- or positive-working imaged elements, for example as lithographic printing plates. The imageable elements also include a radiation absorbing compound and a solvent-resistant polymer comprising pendant phosphoric acid groups, pendant adamantyl groups, or both. When this polymer comprises pendant adamantyl groups, they are connected to the polymer backbone through a urea or urethane group. The imageable elements have improved chemical resistance and thermal bakeability from the presence of the unique solvent-resistant polymer.Type: GrantFiled: December 1, 2005Date of Patent: July 24, 2007Assignee: Eastman Kodak CompanyInventors: Shashikant Saraiya, Jayanti Patel, Ting Tao, Kevin B Ray, Frederic E.

Patent number: 6981446Abstract: The present invention provides a method of imaging a printing plate precursor in which a printing plate precursor including a substrate and an image forming layer is imagewise contacted with a catalyst, for example, by imagewise ink-jet application. The image forming layer is then heated and developed in a suitable developer liquid such that portions of the image forming layer that are contacted with the catalyst resist development while portions of the image forming layer that are not contacted with the catalyst are removed during development.Type: GrantFiled: July 8, 2003Date of Patent: January 3, 2006Assignee: Eastman Kodak CompanyInventors: Kevin Barry Ray, John Kalamen
