Abstract: In various embodiments, 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: 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, one or more infrared radiation absorbing compounds, and an inorganic phosphoric acid or inorganic phosphoric acid precursor. The lithographic printing plate precursors can be designed for either off-press or on-press development after IR imaging.

Abstract: A device as well as method for treating without developing an imagewise exposed lithographic printing plate is disclosed. The device comprises a structure for providing a treating solution to the exposed plate. The exposed plate comprises on a substrate a photosensitive layer having hardened areas and non-hardened areas (for negative plate) or solubilized areas and non-solubilized areas (for positive plate). The non-hardened or solubilized areas of said photosensitive layer is removable with ink and/or fountain solution on a lithographic press. The treatment of the imagewise exposed plate allows one or more enhanced properties for the plate before on-press development, such as improved white light stability, enhanced or formation of visible image, improved hydrophilicity, or improved on-press developability.
