摘要： Lithographic printing plates can be prepared and made ready for lithographic printing without wet development or processing. A positive-working lithographic printing plate precursor is exposed to ablating infrared radiation of an energy of at least 1 J/cm2 to form a lithographic printing plate ready for lithographic printing. The positive-working lithographic printing plate precursor has a hydrophilic aluminum substrate, and on the substrate, a crosslinked hydrophilic inner layer, and an oleophilic surface layer that is chemically bonded to the crosslinked hydrophilic inner layer. An intermediate layer provided between the crosslinked hydrophilic inner and oleophilic surface layers. Either this intermediate or the oleophilic surface layer, or both, generally includes an infrared radiation absorbing compound.

摘要： A method of making imaged elements such as lithographic printing plates is achieved by imagewise exposing a positive-working imageable element using energy of less than 300 mJ/cm2 to provide exposed and non-exposed regions. The imaged element is developed using an alkaline, silicate-free solution containing a carbonate to remove predominantly only the exposed regions to provide an image. The imageable element comprises a substrate and a radiation absorbing compound, and has an imageable layer on the substrate that comprises a developability-enhancing compound and a poly(vinyl acetal) in which at least 25 mol % of its recurring units comprise pendant nitro-substituted phenolic groups.

摘要： Lithographic printing plates can be prepared and made ready for lithographic printing with simple wet development or processing. A positive-working lithographic printing plate precursor is exposed to infrared radiation for example at 200 to 300 mJ/cm2. The exposed precursor can be simply processed with water or an aqueous solution, and uniformly exposed to radiation, heat, or both. The positive-working lithographic printing plate precursor has a hydrophilic aluminum substrate, a crosslinked hydrophilic inner layer, and an oleophilic surface layer that is weakly bonded to the crosslinked hydrophilic inner layer.

摘要： Positive-working lithographic printing plate precursors comprise a substrate surface having an average oxide pore diameter of 15 to 80 nm. On this, a crosslinked hydrophilic inner layer is formed using a formulation comprising: (1) a hydrophilic polymer having recurring —CH2—CH(OH)— units, (2) a crosslinking agent for these units having at least two aldehyde groups, and (3) an acidic compound. An oleophilic outer layer formulation comprises: (a) an infrared radiation absorber, and (b) an oleophilic polymer having at least 10 mol % randomly recurring —CH2—CH(OH)— units, within an organic solvent solution, and dried to form a composite structure. The composite structure is heated so its surface exhibits less than 10% optical density change within a first rectangular area (width W1 and length L1) centered inside a second rectangular area (width W2 and length L2), where the surface is subjected to 1000 rubs according to ASTM D3181 using the organic solvent solution.
