Abstract: Multi-layer, negative working imageable elements useful as lithographic printing plate precursors are disclosed. The elements contain, in order, a support; an underlayer; and an imageable layer. The imageable layer comprises a negative working imageable composition; and the underlayer is soluble or dispersible in a developer. Elements that can be imaged with ultraviolet or visible radiation and elements that can be imaged with infrared radiation or with heat are disclosed.

Abstract: The present invention provides a method of imaging a printing plate precursor in which a printing plate precursor including a substrate and an image forming layer is imagewise contacted with a catalyst, for example, by imagewise ink-jet application. The image forming layer is then heated and developed in a suitable developer liquid such that portions of the image forming layer that are contacted with the catalyst resist development while portions of the image forming layer that are not contacted with the catalyst are removed during development.

Abstract: The presence of unwanted ink-receptive sections on developed positive-working lithographic plates due to shading by plate-holding clamps during imaging, is avoided by the use of clamps that are substantially transparent to the imaging radiation. In the case where the plate precursors can be imaged by heat, the presence of unwanted unexposed sections can also be avoided by selectively heating those sections shaded by the clamps, while avoiding heating the image section of the plate.

Abstract: Positive-working thermally imageable elements, useful as printing plate precursors and having reduced ablation when thermally imaged, and methods for their preparation are disclosed. In one aspect, the elements contain a hydrophilic substrate, an underlayer, a barrier layer, and a top layer. The underlayer comprises a photothermal conversion material.
