    Abstract: A radiation-sensitive composition and negative-working imageable element includes a free radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of the free radically polymerizable component upon exposure to imaging radiation, a radiation absorbing compound, and particles of a poly(urethane-acrylic) hybrid that are distributed throughout the composition forming an imageable layer in the element. Imaging can be accomplished at a wide range of wavelengths from about 150 to about 1500 nm, and development can be accomplished using an organic solvent-based developer, warm water, plate cleaner, or on-press using a combination of a lithographic printing ink and a fountain solution.

    Abstract: Negative-working imageable elements that can be imaged using infrared radiation comprise an imageable layer and a protective overcoat on a hydrophilic substrate. The imageable layer includes an IR-sensitive cyanine dye. The protective overcoat predominantly comprises one or more poly(vinyl alcohol) resins, each of which has a hydrolysis level of 85% or less. The use of this particular overcoat composition used in combination with the IR-sensitive cyanine dye provides improved tolerance to fogging by white light while maintaining desired imaging speed.

    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.
