    摘要: A negative-working imaging member can be used as a lithographic printing plate without ablation. The imaging member comprises a support and an imaging layer that includes a dispersion of at least 0.05 g/m 2 of a cyanoacrylate polymer that is thermally degradable below 200°C, a photothermal conversion material that is present in an amount to provide a dry weight ratio to the cyanoacrylate polymer of from 0.02:1 to 0.8:1, and a hydrophilic binder to provide a dry weight ratio of a hydrophilic binder to the cyanoacrylate polymer of up to 1:1. Thermal imaging energy causes the exposed areas of the imaging layer to adhere to the support while unexposed areas can be readily washed off and/or simultaneously inked for press runs.

    摘要: The present invention is a method of producing an imaging support which includes providing a support, simultaneously coating on a side of the support; a transparent magnetic recording layer including magnetic particles, a polymeric binder and an organic solvent, and a lubricating overcoat layer farthest from the support, the lubricating overcoat layer including a lubricant selected form the general formulas I, II or III:
       wherein general formula I comprises:
    wherein X is selected from the group consisting of esters, amides, ethers, or methylene, a is from 10 to 500, and b is from 4 to 3000, and the general formula I has a molecular weight at least 800;
       wherein general formula II comprises:
    wherein Y is selected from the group consisting of, -C- and-N-, Z is selected from the group consisting of esters, amides, and a carbon-carbon bond, R is selected from the group consisting of methyl, and hydrogen or may be absent if Y equals nitrogen, c is from 1 to 2, d is from 4 to 3000, e is from 10 to 30, and the general formula II has a molecular weight of from 800 to 500,000, preferably from 3000 to 100,000;
       wherein general formula III comprises:
    wherein R' is selected from the group consisting of methyl, phenyl, substituted aliphatic groups, unsubstituted aliphatic groups, substituted aromatic groups, and unsubstituted aromatic groups; wherein f is from 4 to 3000, and g is from 10 to 30, and the general formula III has a molecular weight of from 800 to 500,000 and preferably are between 3000 and 100,000, and an organic solvent. The present invention also includes a photographic element produced by the method
