Patent number: 8383319Abstract: Lithographic printing plate precursors have been designed so that they can be stored, shipped, and used in stacks without interleaf paper between individual precursors. This is achieved by incorporating polymeric particles having an average diameter of from about 3 to about 20 ?m into the outermost precursor layer such as an imagable layer or topcoat. The polymeric particles comprise a core of a crosslinked polymer and have grafted hydrophilic polymeric surface groups that are grafted onto the particle surfaces by polymerizing hydrophilic monomers in the presence of the crosslinked polymeric particles. The lithographic printing plates can be either negative- or positive-working elements.Type: GrantFiled: August 25, 2009Date of Patent: February 26, 2013Assignee: Eastman Kodak CompanyInventors: Jianbing Huang, Shashikant Saraiya, Frederic E.
