The single processing solution (developer) comprises at least 2.5 weight % of a nonionic surfactant having an HLB value greater than 15 and at least 5 weight % of a polar organic solvent. Processing is accomplished without replenishment and reduced sludge formation is seen at the end of the processing cycle.

    Abstract: Images can be provided using a method comprising thermally imaging a negative-working imageable element to provide an imaged element with exposed regions and non-exposed regions, the exposed regions consisting essentially of coalesced core-shell particles, and developing the imaged element on-press to remove only the non-exposed regions using a lithographic printing ink, fountain solution, or both. The imageable element comprises a single thermally-sensitive imageable layer consisting essentially of an infrared radiation absorbing compound and core-shell particles that coalesce upon thermal imaging. The core of the core-shell particles is composed of a hydrophobic thermoplastic polymer, the shell of the core-shell particles is composed of a hydrophilic polymer that is covalently bonded to the core hydrophobic thermoplastic polymer, and the thermally-sensitive imageable layer comprises less than 10 weight % of free polymer.

    Abstract: Lithographic printing plates can be provided by imagewise exposing a negative-working lithographic printing plate precursor comprising an aluminum-containing substrate having thereon an imageable layer, to provide exposed and non-exposed regions in the imageable layer. This imaged element is then processed to remove the non-exposed regions in the imageable layer and to gum the resulting image in a single step without an intermediate rinsing step by using an aqueous alkaline solution having a pH of at least 9. The aqueous alkaline solution includes an organic amine having a boiling point of less than 300° C., a film-forming hydrophilic polymer, and optionally an anionic or nonionic surfactant.
