    Abstract: This patent describes an on-press developable thermosensitive lithographic plate having on a substrate a thermosensitive layer comprising an ethylenically unsaturated monomer, an infrared absorbing dye, and an onium or borate salt free radical initiator. The plate can be imagewise exposed with an infrared laser on a plate exposure device, and then mounted on a lithographic press for on-press development with ink and/or fountain solution and lithographic printing. No regular development process with a liquid developer is needed after exposure. Alternatively, the plate can be imagewise exposed with an infrared laser while mounted on a plate cylinder of a lithographic press, on-press developed with ink and/or fountain solution, and then print images to the receiving sheets.

    Abstract: This invention relates to an imageable element that can be imaged and developed to produce a printing plate. The imageable element comprises a substrate and a radiation-sensitive imageable composition applied to the substrate. The imageable composition comprises (a) a first layer having (i) a photosensitive composition which undergoes a decrease in solubility in developer upon absorption of actinic radiation and (ii) an inhibitor, and (b) a second layer comprising an ink-repellent polymeric material. In one embodiment, the inhibitor is activated by heat or radiation of longer wavelength than actinic radiation. Upon activation, the inhibitor retards the solubility decrease of the photosensitive composition upon absorption of actinic radiation. In another embodiment, the inhibitor initially retards the solubility decrease of the photosensitive composition upon absorption of actinic radiation. However, the inhibitor is deactivated by heat or radiation of longer wavelength than actinic radiation, and upon deactivation the inhibitor no longer retards the solubility decrease of the photosensitive composition.
