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： Infrared radiation-sensitive, positive-working lithographic printing plate precursors have improved scratch resistance in their outermost imageable layer because that layer comprises a unique combination of first and second alkali solution-soluble or -dispersible resins. The first alkali solution-soluble or -dispersible resin is an acid-functionalized novolak or acid-functionalized resole resin. The second alkali solution-soluble or -dispersible resin is a polyurethane or polyurethane urea comprising a polysiloxane unit segment in the polyurethane or polyurethane urea backbone or a side chain.

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.
