摘要： A lithographic processing solution having a pH of less than 12 and comprising at least 0.001 and up to and including 1 weight % of a water-soluble or water-dispersible, non-IR-sensitive compound that has a heterocyclic moiety with a quaternary nitrogen in the 1-position of the heterocyclic ring, and having one or more electron donating substituents attached to the heterocyclic ring, at least one of which electron donating substituents is attached in the 2-position. The processing solution can be used to develop both single-layer and multi-layer positive-working lithographic printing plate precursors that have been imaged using infrared radiation.

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.

摘要： Single- and multi-layer positive-working imageable elements include an ink receptive outer layer that includes inorganic, non-metallic, inert discrete particles, such as nano-sized silica, aluminum oxide, or titanium dioxide particles. The presence of these particles in the outermost layer improves the abrasion and scratch resistance of the elements.
