Patent number: 8936902Abstract: An infrared radiation-sensitive positive-working imageable element has a substrate and single imageable layer that includes a first polymeric binder having urethane or urea moieties in its backbone. The first polymeric binder is also insoluble in water and soluble in a weakly alkaline solution. This imageable element can be imaged and processed using weakly alkaline processing solutions that are free of silicates and metasilicates, which processing solutions may also be used to “gum” the imaged and developed printing surface.Type: GrantFiled: November 20, 2008Date of Patent: January 20, 2015Assignee: Eastman Kodak CompanyInventors: Anthony P. Kitson, Kevin B. Ray, Shashikant Saraiya, Frederic E. Mikell, Jayanti Patel

Patent number: 8323874Abstract: A multi-layer, positive-working lithographic printing plate precursor can be imaged with infrared radiation and processed in a single step using a single processing solution that has a pH greater than 6 and up to about 11. This single processing solution both develops the imaged precursor and provides a protective coating that need not be rinsed off before lithographic printing.Type: GrantFiled: January 22, 2008Date of Patent: December 4, 2012Assignee: Eastman Kodak CompanyInventors: Kevin B. Ray, Anthony P. Kitson

Patent number: 8062827Abstract: Positive-working imageable elements can be used to prepare lithographic printing plates. These elements have at least two layers (inner and outer) arranged on a suitable substrate. The inner layer that is closer to the substrate includes one or more polymeric binders that include pendant oxazoline groups and acid groups that are reactive with the oxazoline groups during a post-baking step after development. The resulting imageable elements are more quickly baked in this manner to provide improved run length and resistant to press chemicals.Type: GrantFiled: August 11, 2008Date of Patent: November 22, 2011Assignee: Eastman Kodak CompanyInventors: Anthony P. Kitson, Larisa Novoselova

Patent number: 7291440Abstract: Thermally imageable multilayer imageable elements useful as lithographic printing plate precursors that have good solvent resistance are disclosed. The underlayer of the imageable element comprises an acidic copolymer that comprises, in polymerized form, about 10 mol % to about 75 mol % of one or more monomers of the formula: CH2?CH(R1)-Z-X—NH—CO—NH—C6H3—(R2)(CO2H); in which: R1 is H or CH3; R2 is H or OH; Z is —C6H4— or —C(O) —Y—; Y is —O— or —NH—; and X is selected from —C(CH3)2—, —CH(CH3)— and —(CH2)n—, in which n is an integer from 1 to 12.Type: GrantFiled: May 16, 2005Date of Patent: November 6, 2007Assignee: Eastman Kodak CompanyInventors: Kevin B.

Publication number: 20070172764Abstract: A positive-working imageable element comprises inner and outer layers and a radiation absorbing compound such as an IR absorbing dye. The inner layer includes a first polymeric material. The ink receptive outer layer includes a second polymeric binder comprising a polymer backbone and an —X—C(=T)-NR—S(?O)2— moiety that is attached to the polymer backbone, wherein —X— is an oxy or —NR?— group, T is O or S, R and R? are independently hydrogen, halo, or an alkyl group having 1 to 6 carbon atoms. After thermal imaging, the element can be developed using an alkaline developer. Use of the particular second polymeric binder reduces sludging in the developer. Its dissolution rate in the developer is slow enough to resist developer attack in the non-imaged areas of the outer layer but rapid enough for the second polymeric binder to be quickly loosened from imaged areas and kept suspended or dissolved for a considerable time.Type: ApplicationFiled: October 23, 2006Publication date: July 26, 2007Inventors: Shashikant Saraiya, Anthony P. Kitson, Frederic E. Mikell, Larisa Novoselova
