摘要： Positive-working lithographic printing plate precursors have an inner layer that includes a polymeric binder having an acid number of at least 30 mg KOH/g of polymer to and including 150 mg KOH/g of polymer, at least 3 weight % of recurring units derived from one or more N-alkoxymethyl(alkyl)acrylamides or alkoxymethyl(alkyl)acrylates, at least 2 weight % of recurring units having pendant 1H-tetrazole groups, and at least 10 weight % of recurring units having pendant cyano groups. The use of such polymeric binders in the inner layer provides good bakeability and chemical solvent resistance.

摘要： On-press developable, negative-working, infrared radiation-sensitive lithographic printing plate precursors have an imageable layer on a substrate. The imageable layer includes a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to infrared radiation, a polymeric binder, a first infrared radiation absorbing compound that has a tetraaryl pentadiene chromophore, and a second infrared radiation absorbing compound that is different than the first infrared radiation absorbing compound. The first IR absorbing compound absorbs in both the IR and visible regions of the electromagnetic spectrum and provides coloration for visual inspection of the lithographic printing plates.

摘要： Electrochemically grained and anodized aluminum supports are treated with a post-treatment coating solution containing a polymer derived at least in part from vinyl phosphonic acid and phosphoric acid. This post-treated support is useful as substrates in the preparation of lithographic printing plate precursors. The post-treatment substrate treatment enables wide latitude in manufacturing and compatibility with silicate-free developers to achieve negligible background staining and oxide attack.
