    Abstract: Ablation-type printing plates having increased shelf-life are produced using a melamine resin free of water prior to use. A representative production sequence includes providing a substrate having an oleophilic surface; coating, over the substrate, an oleophilic resin composition having (A) a resin phase consisting essentially of a melamine resin substantially free of water and a resole resin, the resole resin being present in an amount ranging from 0% to 28% by weight of dry film, (B) a near-IR absorber dispersed within the resin phase, and (C) a sulfonic acid catalyst dispersed within the resin phase and being present in an amount ranging from 0.7% to 1.6% by weight of dry film; curing the resin composition to produce a dry film; following resin curing, coating an oleophobic polymer composition over the cured resin composition; and curing the oleophobic polymer composition.

    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: A downhole tool has a mandrel with a sealing element disposed thereabout. The sealing element is movable from an unset position to a set position in which the sealing element engages the well. Extrusion limiters are positioned at the ends of the sealing element. The extrusion limiters have first and second layers and the first and second layers are different materials. The second layer may be made up of a plurality of discs. At least one of the discs may be a disc with an irregularly shaped outer peripheral edge and a generally circular inner peripheral edge. A plurality of the discs with the irregularly shaped outer edge may be stacked and may be stacked with a generally circular or ring-shaped segmented disc. The first and second layers are stacked and then molded into a final shape for placement at the ends of the sealing element.

    Abstract: A slip for use in the anchoring of a downhole tool in the well casing is provided. The anchors include a plurality of buttons and at least one wicker. The slip is positioned about a mandrel and radially expands upon the application of force. The buttons and wicker first engage the casing in response to a first force, and the wicker deformably engages the casing in response to a second force. The second force causes the wicker to cut into and deform the casing, thereby anchoring the downhole tool for high-pressure operations.
