Patent number: 10012904Abstract: A coating for use with a hydrophilic sheet substrate to form a lithographic printing plate precursor, including at least one Compound A silane compound and at least one Compound B phosphinic acid or organic derivative thereof. Compounds A and B experience a synergistic interaction which substantially increases adhesion to the substrate of areas imaged by radiation. The resulting plate is exhibits high on-press durability suitable for high volume commercial uses without a preheat step prior to development, even when imaged with lower levels of radiation such as violet lasers. A method of preparing a lithographic printing plate includes imagewise exposing the coating on a surface of a hydrophilic substrate to violet radiation and developing in an alkaline aqueous solution without preheating.Type: GrantFiled: October 24, 2014Date of Patent: July 3, 2018Assignee: Mark'Andy Inc.Inventor: Anthony Paul Kitson

Publication number: 20150053103Abstract: A method for producing a lithographic plate from a negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. The steps include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas at an initial double bond conversion rate including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and subjecting the upper surface of the plate to blanket post treatment energy, which further reacts the retained unreacted material in the image areas to increase the initial double bond conversion rate, producing a lithographic printing plate with enhanced durability.Type: ApplicationFiled: September 5, 2014Publication date: February 26, 2015Inventors: Howard A. Fromson, William J. Ryan, Anthony Paul Kitson, Brian L. Anderson

Patent number: 7026254Abstract: A precursor that may be imaged by heat is made up of a substrate, for example a copper board, and a composite layer structure composed of two layers. Preferably, the first layer is composed of an aqueous developable polymer mixture containing a photothermal conversion material, which is contiguous to the substrate. The second layer of the composite is composed of one or more non-aqueous soluble polymers, which are soluble or dispersible in a solvent which does not dissolve the first layer. The precursor is exposed with an infrared laser or a thermal print head, and upon aqueous development, the exposed regions are removed, revealing regions of the substrate surface able to be etched or otherwise treated. The second layer may also contain a photothermal conversion material. Alternatively, the composite layer may be free of photothermal conversion material when thermal imaging is carried out using a thermal print head. The precursor may be used, for example, as a mask precursor or electronic part precursor.Type: GrantFiled: April 2, 2003Date of Patent: April 11, 2006Assignee: Eastman Kodak CompanyInventors: Kevin Barry Ray, Anthony Paul Kitson
