摘要： Substrates for lithographic printing plate precursors and lithographic printing plate precursors are disclosed. The substrates comprise an aluminum or aluminum alloy support and the a layer of interlayer material on the support. The interlayer material is a co-polymer that comprise (1) acid groups and/or phosphonic acid groups, and (2) silyl groups substituted with three alkoxy and/or phenoxy groups. The lithographic printing plate precursors additionally comprise an imageable layer over the interlayer.

摘要： A radiation-sensitive composition includes a radically polymerizable component, initiator composition, a radiation absorbing compound, and a polymeric binder having recurring units that are derived from various ethylenically unsaturated polymerizable monomers provided that at least 40 mol % of the recurring units have a tertiary carbon atom in the backbone and the rest of the recurring units have a secondary or quaternary carbon atom in the backbone. This composition can be used to provide negative-working imageable elements that can be imaged and developed to provide lithographic printing plates that have desired imaging speed and excellent run length without the need for a post-exposure backing step.

摘要： Both single-layer and multilayer imageable elements have a substrate and at least one imageable layer. The elements can be used to prepare either negative- or positive-working imaged elements, for example as lithographic printing plates. The imageable elements also include a radiation absorbing compound and a solvent-resistant polymer comprising pendant phosphoric acid groups, pendant adamantyl groups, or both. When this polymer comprises pendant adamantyl groups, they are connected to the polymer backbone through a urea or urethane group. The imageable elements have improved chemical resistance and thermal bakeability from the presence of the unique solvent-resistant polymer.

摘要： A thermal lithographic printing plate, which can be imaged by thermal energy typically by imagewise exposure with an infrared emitting laser, a thermal printing head, etc., is made up of a hydrophilic substrate, and a composite layer structure composed of two layer coatings. Preferably, the first layer of the composite is composed of an aqueous developable polymer mixture containing a solubility inhibiting material and a photothermal conversion material which is contiguous to the hydrophilic substrate. The second layer of the composite is insoluble in the aqueous solution, is ink receptive, and is composed of one or more non-aqueous soluble polymers which are soluble or dispersible in a solvent which does not dissolve the first layer. The plate is exposed with an infrared laser or a thermal print head, and upon aqueous development of the imaged plate, the exposed portions are removed exposing hydrophilic substrate surfaces receptive to conventional aqueous fountain solutions. The unexposed portions contain the ink-receptive image areas. The second layer may also contain a photothermal conversion material. Alternatively, the composite layer may be free of photothermal conversion material when thermal imaging is carried out using a thermal printing head.
