    摘要： A negative-working, imageable element comprises a substrate and an IR-sensitive imageable layer comprising a dispersion of nanofibers of a preformed IR-sensitive polymer. The nanofibers can be composed of polyaniline, polypyrrole, or polythiophene. The IR-sensitive imageable layer containing the nanofibers can be imaged using infrared radiation and used for printing without further processing. Thus, both imaging and printing can be carried out on-press.

    摘要： A negative-working imageable element having an imageable layer on a substrate can be used to form an imaged element by imagewise exposing it to form exposed and non-exposed regions in the imageable layer. The imageable element also has a water-soluble topcoat disposed on the imageable layer. With or without a preheat step, the water-soluble topcoat is at least partially removed with water or an aqueous solution that incompletely or not at all removes the non-exposed regions of the imageable layer. The element is then mounted in a printing press and contacted with a fountain solution, a lithographic printing ink, or a combination of a fountain solution and a lithographic printing ink, thereby removing non-exposed regions of the imageable layer at the beginning of the printing operation.

    摘要： A method to reduce effluence during or immediately after imaging of a printing plate is described. In one embodiment of the invention, the method comprises: (a) applying to a substrate a coating composition comprising a photothermal converter and at least one polymer comprising thiosulfate groups to obtain a coating; and (b) applying a water soluble topcoat to the coating. Preferably, the water soluble topcoat does not comprise a photothermal converter. In another embodiment of the invention, the method comprises applying to a substrate a composition comprising: (a) a photothermal converter; (b) at least one polymer comprising thiosulfate groups; and (c) an additive selected from the group consisting of diazonium, iodonium, copper(I), alkoxypyridinium or maleimide additives.

    摘要： The present invention provides an imageable element including a lithographic substrate and an imageable layer disposed on the substrate. The imageable layer includes a radically polymerizable component, an initiator system, and a polymeric binder. The imageable element further includes a tetraarylborate salt. The presence of the tetraarylborate salt may provide improved imaging speed and may enhance press life due to better adhesion between the imageable layer and the substrate. The tetraarylborate salt may be present in the imageable layer, an interlayer, or a separate layer between the substrate and the imageable layer. The imageable element may be imaged and mounted on-press without a separate development step.
