摘要： Radiation-sensitive compositions and imageable elements include a polymeric or non-polymeric component in an imageable layer, which component includes 1H-tetrazole groups. The non-polymeric components can be radically polymerizable compounds. The polymeric components can have 1H-tetrazole groups that are pendant to the backbone. The use of such components in negative- or positive-working imageable elements provides high photospeed and improved developability for providing imaged and developed elements, such as lithographic printing plates that show improved chemical resistance and run length.

摘要： A negative-working lithographic printing plate precursor comprises a negative-working radiation-sensitive imageable layer and an outermost layer comprising a vinyl alcohol copolymer comprising at least one unit of each of the (a), (b), and (c) recurring units, in any order, defined in the disclosure. The (c) recurring units are present in the vinyl alcohol copolymer in an amount of at least 0.5 mol %, based on the total recurring units. These precursors can be used to prepare lithographic printing plates either on-press or off-press after imaging using near-UV, visible, or infrared radiation.

摘要： Both positive-working and negative-working imageable element can have a radiation-sensitive imageable layer that has at least one pigment colorant that does not change color when heated, and at least one dye that can change color when heated. The dye is soluble in the solvent or mixture of solvents used to coat the radiation-sensitive imageable layer on a substrate and the pigment colorant is not. This combination of pigment colorant and dye provide excellent image contrast after imaging, development, and postbaking. The pigment colorant and the dye independently have a maximum absorption of from about 480 to about 700 nm.
