摘要： Positive-working imageable elements having improved sensitivity, high resolution, and solvent resistance are prepared using a water-insoluble polymeric binder comprising vinyl acetal recurring units that have pendant hydroxyaryl groups, and recurring units comprising carboxylic acid aryl ester groups that are substituted with a cyclic imide group. These imageable elements can be imaged and developed to provide various types of elements including lithographic printing plates.

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： Positive-working imageable elements can be imaged and processed using a processing solution that comprises at least 0.03 N of an organic amine or a mixture thereof, whose conjugated acids have a pKa greater than 9 and a boiling point greater than 150° C. The imageable element is a single-layer, infrared radiation-sensitive positive-working imageable element comprising a substrate and an infrared radiation absorbing compound. It also has an imageable layer that comprises a developability-enhancing compound and a poly(vinyl acetal) in which at least 25 mol % of its recurring units comprise pendant phenol, naphthol, or anthracenol groups that are substituted with one or more electron-withdrawing groups.

摘要： A method of making imaged elements such as lithographic printing plates is achieved by imagewise exposing an infrared radiation-sensitive positive-working imageable element to provide exposed and non-exposed regions. The imaged element is developed using a single processing solution having a pH of from about 9 to about 11.5 and containing carbonate ion and at least 1 weight % of one or more anionic surfactants, to remove predominantly only the exposed regions to provide an image and to provide a protective coating on the imaged surface. 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.
