    Abstract: A radiation-sensitive composition includes an initiator composition, a radiation absorbing compound, and a particulate primary polymeric binder that has a backbone comprising multiple urethane moieties and further comprises side chains comprising free radically polymerizable groups attached to the backbone. This primary polymeric binder can be used in place of or in addition to a conventional free radically polymerizable component. This composition can be used to provide negative-working imageable elements that can be imaged and developed to provide lithographic printing plates.

    Abstract: 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.
