Abstract: A recording medium comprises an oleophilic substrate and, thereover, a topmost oleophobic layer comprising a cured polymeric silicone matrix that consists essentially of the addition-cure reaction product of a vinyl-functional polydialkylsiloxane and a silane cross-linking agent. The vinyl-functional polydialkylsiloxane has a molecular weight ranging from 30,000 to 75,000 or 110,000 to 130,000. If the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 30,000 to 75,000, the molar ratio of silane groups to vinyl groups is within the range of about 11:1 to about 25:1; and if the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 110,000 to 130,000, the molar ratio of silane groups to vinyl groups is from about 5:1 to about 27:1. The recording medium may be used as a lithographic printing plate.

Abstract: A positive-working, ablation-imagable lithographic printing plate precursor can be imaged and used for lithographic printing without wet processing. This precursor has a sulfuric acid or phosphoric acid anodized aluminum-containing substrate, a crosslinked hydrophilic inner layer comprising a crosslinked polymer derived by using a crosslinking agent that comprises at least two aldehyde groups, and an acidic compound. Over the crosslinked hydrophilic inner layer is an oleophilic outer layer comprising an infrared radiation absorber and an oleophilic polymer. The precursor also has a copolymer comprising randomly recurring units derived from each of a (meth)acrylamide and vinyl phosphonic acid. This copolymer is present either within the crosslinked hydrophilic inner layer, as part of a different copolymer layer between the crosslinked hydrophilic inner layer and the substrate, or in both places.
