    Abstract: The present invention provides methods of imagewise exposing a thermally sensitive composition formed from a nanopaste comprising inorganic nanoparticles, a carrier, and preferably certain polymeric binders. The composition has been applied to a substrate and treated to improve adhesion. Exposure affects the solubility of exposed portions of the applied and treated layer relative to unexposed portions of the applied layer. The imaged layer is then developed on-press with a fountain solution, lithographic ink, or both, to remove the exposed portions or unexposed portions of the layer to form an image in a printing plate.

    Abstract: An imaged and developed element, such as a lithographic printing plate, is provided by infrared radiation imaging of a negative-working imagable element having an outermost imagable layer that includes a free radically polymerizable component, a free radical initiator composition comprising a diaryliodonium borate, and an infrared radiation absorbing compound. The imagable layer also includes a polymeric binder that is represented by the following Structure (I): -(A)w-(A′)w′-  (I) wherein A represents recurring units comprising a pendant reactive vinyl group, A′ represents recurring units other than those represented by A, w is from about 1 to about 70 mol %, and w′ is from about 30 to about 99 mol %. The imagewise exposed element is developed with a gum to remove only the non-exposed regions. The gum has a pH greater than 7 and up to about 11 and at least 1 weight % of an anionic surfactant.

    Abstract: An imaged and developed element, such as a lithographic printing plate, is provided by infrared radiation imaging of a negative-working imageable element having an outermost imageable layer that includes an acid generating compound that generates acid upon exposure to imaging infrared radiation, an infrared radiation absorbing compound, an acid activatable crosslinking agent that has acid activatable reactive groups, and a polymeric binder that is capable of undergoing an acid-catalyzed condensation reaction with the crosslinking agent. The imaged element is heated at from about 120 to about 150° C. for up to two minutes, and then developed with a single processing solution to remove only the non-exposed regions and to provide a protective layer prior to lithographic printing.
