Abstract: A non-ablative negative-working imageable element has first and second polymeric layers under a crosslinked silicone rubber layer. These elements can be used in a simple method to provide lithographic printing plates useful for waterless printing (no fountain solution). Processing after imaging is relatively simple using either water or an aqueous solution containing very little organic solvent to remove the imaged regions. The crosslinked silicone rubber layer is ink-repelling and only the first layer that is closest to the substrate contains an infrared radiation absorbing compound to provide thermal sensitivity.

Abstract: Negative lithographic printing plate having on a substrate a photosensitive layer comprising an alkaline soluble polymeric binder, an alkaline insoluble polymeric binder, a polymerizable monomer, and an initiator is described. The photosensitive layer is imagewise exposed with a radiation to cause hardening in the exposed areas, and then developed to remove the non-hardened areas. The combination of both alkaline soluble polymeric binder and alkaline insoluble polymeric hinder in a photosensitive layer can give excellent combined durability, developability, and coatability.
