    摘要： A method for forming an image useful as a lithographic printing plate is disclosed. The imageable precursor comprises a water solubilized phenolic resin made up of an insoluble phenolic resin and a surfactant. The precursor can be imaged with an imaging solution, either off press or on press, using ink jet imaging techniques. The resulting imaged precursor can be developed using an aqueous liquid, such as water or a fountain solution, either off press or on press.

    摘要： 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.

    摘要： The present invention includes a radiation-imageable element for lithographic printing having a hydrophilic anodized aluminum base with a surface having pores and a image-forming layer having polymer particles coated on the aluminum base. The ratio of the average pore diameter to the average particle diameter is from 0.4:1 to 10:1. The present invention further includes a method of producing the imaged element. The method includes the steps of imagewise exposing the radiation-imageable element to radiation to produce exposed and unexposed regions and contacting the imagewise exposed radiation-imageable element and a developer to remove the exposed or the unexposed regions.
