摘要： A positive-working thermal imaging element, which can be imaged by thermal energy is made up of a hydrophilic substrate, and a composite layer structure composed of two layer coatings. The first layer of the composite is composed of an aqueous developable polymer mixture containing a photothermal conversion material which is contiguous to the hydrophilic substrate. The second layer of the composite 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 second layer may also contain a photothermal conversion material. The element is exposed with an infrared laser or a thermal print head. Upon aqueous development of the imaged unexposed portions are ink-receptive.

摘要： A posiitive-working thermal imaging element, which can be imaged by thermal energy is made up of a hydrophilic substrate, and a composite layer structure composed of two layer coatings. The substrate has a roughened surface of average roughness Ra in the range from 0.1 to 0.8 µm, preferably 0.1 to 0.4 µm. The first layer of the composite is composed of an aqueous developable polymer mixture containing a photothermal conversion material which is contiguous to the hydrophilic substrate. The second layer of the composite 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 second layer may also contain a photothermal conversion material. The positive-working thermal imaging element is exposed with an infrared laser or a thermal print head. Upon aqueous development of the imaged positive-working thermal imaging element unexposed portions are ink-receptive.

摘要： The present invention relates to a polymerizable coating composition suitable for the manufacture of printing plates, which may be developable on-press. The coating composition comprises (i) a polymerizable compound and (ii) a polymeric binder comprising polyethylene oxide segments, wherein the polymeric binder is selected from the group consisting of at least one graft copolymer comprising a main chain polymer and polyethylene oxide side chains, a block copolymer having at least one polyethylene oxide block and at least one non-polyethylene oxide block, and a combination thereof. The invention is also directed to an imageable element comprising a substrate and the polymerizable coating composition.

摘要： Infrared absorbing compounds that absorb at 800 nm ± 50 nm and at 1050 nm ± 50 nm, the two different regions of the infrared spectrum typically used for imaging, are disclosed. Thermally imageable elements that comprise these infrared absorbing compounds can be imaged with radiation in either of these two regions of the infrared spectrum. The elements are especially useful as lithographic printing plate precursors.

摘要： In one embodiment, the invention is directed to soft proofing system that incorporates one or more of the features to promote controlled viewing conditions. For example, the invention can provide a soft proofing system in which an administrator can control the proofing process by limiting or restricting the ability to view an image until acceptable viewing conditions have been met. The image may have an associated set of viewing conditions that can be specified by the administrator. Then, when the image is sent to a viewing station, the ability to view the image can be restricted until one or more viewing conditions have been met at that viewing station. With controlled viewing conditions, the soft proof reviewers obtain more uniform output. In this manner, the system can provide safeguards to ensure that the images viewed at the viewing station have acceptable color accuracy.

摘要： Imageable elements with improved dot stability are disclosed. The imageable elements comprise a layer of an imageable composition over a support. The imageable composition comprises an infrared absorbing compound, an acid generator, an acid activatable crosslinking agent, a polymeric binder, and about 0.01 wt% to 1 wt% of an added onium compound. The elements may be thermally imaged and developed to produce images useful as lithographic printing plates.
