    摘要： The present invention relates to negative-working imageable elements that can be used for the manufacture of printing plates. These imageable elements can be developed on on-press by the action of a lithographic printing ink used in combination with either water or a fountain solution. The imageable elements comprise an imageable layer that is not removable in water or fountain solution alone. The imageable layer includes a free radically polymerizable compound, a free radical initiator composition, an infrared radiation absorbing compound, and a polymeric binder comprising poly(alkylene oxide) pendant groups, and preferably additionally pendant cyano groups.

    摘要： Positive-working imageable elements comprise a radiation absorbing compound and inner and outer layers on a substrate having a hydrophilic surface. The inner layer comprises a polymeric material that is removable using an alkaline developer and comprises a backbone and attached groups represented by the following Structure Q: wherein L1, L2, and L3 independently represent linking groups, T1, T2, and T3 independently represent terminal groups, and a, b, and c are independently 0 or 1. The imageable elements have improved resistance to development and printing chemicals and solvents.

    摘要： The present invention provides an imageable element including a lithographic substrate and an imageable layer disposed on the substrate. The imageable layer includes a radically polymerizable component, an initiator system capable of generating radicals sufficient to initiate a polymerization reaction upon exposure to imaging radiation, and a polymeric binder having a hydrophobic backbone and including both constitutional units having a pendant cyano group attached directly to the hydrophobic backbone, and constitutional units having a pendant group including a hydrophilic poly(alkylene oxide) segment. The invention also provides a method for preparing a suitable polymeric binder. The method comprises contacting a combination of co-monomers in a solvent mixture consisting essentially of a (C1–C6) alkanol and water.

    摘要： A plurality of negative-working lithographic printing plate precursors is provided in a stack. Each precursor comprises an aluminum-containing substrate having thereon a single imageable layer and an outermost topcoat that has a dry coating weight equal to or less than 1 g/m2. The non-imaging backside of the substrate is free of polymer coatings and has an average surface roughness (Ra) in both longitudinal and width directions greater than 0.15 μm. In addition, the imageable side of each underlying precursor is arranged in direct contact with the aluminum-containing substrate of the precursor above it without the use of an interleaf paper between the precursors.

    摘要： A method for forming a printing plate from a printing plate precursor having a radiation-sensitive layer, sensitive to radiation in a first frequency spectrum such as the far or near infrared, and to radiation in a second frequency spectrum other than the first frequency spectrum such as visible or ultraviolet. The plate is exposed twice. Once to imaging radiation in the first frequency spectrum and again to radiation in the second frequency spectrum. The second frequency spectrum exposure is done only to the areas of the plate undesirably shaded during the imagewise exposure.
