  • Patent number: 9649834
    Abstract: This disclosure is directed to a material composition that may be usable as a surface component in a plate design for use in variable data digital lithographic image forming devices. The disclosed material composition incorporates infra-red (IR) absorbing filler materials, including carbon black filler material particles in a fluorosilicone polymer or elastomer. The inclusion of the disclosed carbon black material compositions promotes precise heating in a patterning step for a layer of dampening fluid while minimizing harmful byproduct emissions including emissions of trifluoropropionaldehyde (TFPA) resulting from localized heating of a principally fluorosilicone imaging layer. The disclosed homogeneously-dispersed carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.

    Abstract: Radiation-curable silsesquioxane resin materials are employed for micro- and nanolithography. The resin materials can include a radiation-curable silsesquioxane resin and a photo-initiator having low viscosity. The low viscosity of the liquid system allows imprinting with low pressure and low temperature; e.g. room temperature. The resist's dry etching resistance is increased and the cured film is more easily separated from the mask. Due to its high modulus after cure, the material allows the fabrication of micro- and nano-features having high aspect ratios while providing a high throughput. Various pattern sizes, for example, ranging from tens of microns to as small as a few nanometers, may be achieved with the UV-curable material system.

  • Patent number: 8084135
    Abstract: A composition and composite article have improved adherence with an addition-curable material. The composition and therefore the composite article, which includes at least one substrate formed from the composition, include a resin and an additive that is incorporated into the resin. The resin is organic and polymeric and free of ethylenically unsaturated and silicon hydride functional groups. The additive is selected from the group of a fluorine-substituted organopolysiloxane, an amino-functional organopolysiloxane, an unsaturated carboxylic acid or carboxylic acid salt, and combinations thereof. Further, the additive includes a hydrosilylation reactive group present at a surface of the substrate for reaction with the addition-curable material. This improves adherence of the substrate with the addition-curable material. The substrate and the addition-curable material bond together to make the composition article.
