    摘要: Multilayer, positive working, thermally imageable, bakeable imageable elements are disclosed. The elements have a substrate, an underlayer, and a top layer. The underlayer comprises a resin or resins having activated methylol and/or activated alkylated methylol groups, such as a resole resin, and a polymeric material that comprises, in polymerized form about 5 mol % to about 30 mol % of methacrylic acid; about 20 mol % to about 75 mol % of N-phenylmaleimide, N-cyclohexylmaleimide, N-benzylmaleimide, or a mixture thereof; optionally, about 5 mol % to about 50 mol % of methacrylamide; and about 3 mol % to about 50 mol % of a compound represented by the formula: CH2C(R2)C(O)NHCH2OR1, in which R1 is C1 to C12 alkyl, phenyl, C1 to C12 substituted phenyl, C1 to C12 aralkyl, or Si(CH3)3; and R2 is H or methyl. The elements produce bakeable lithographic printing plates that are resistant to press chemistries.

    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: Thermally imageable elements useful as on-press developable lithographic printing plate precursors are disclosed. The elements comprise a substrate and a layer of an imageable composition over the substrate. The imageable composition comprises a photothermal conversion material, particles of a polyurethane polymer, and, optionally, a water soluble polymer. The polyurethane polymer comprises urethane linkages in the main chain, but does not comprise side chain urethane groups.
