  • Patent number: 9346239
    Abstract: A method is used to provide a pattern of a functional material for example on a receiving element. To provide this pattern, a laser-engraveable patternable element is imagewise exposed with laser-engraving radiation. This element has a laser-engraveable layer comprising a thermoplastic elastomeric interpolymer alloy. This interpolymer alloy comprises a non-crosslinked halogenated polymer, a partially crosslinked polyolefin, and a polyester. A laser-engraved patterned element is formed that has a relief image in the laser-engraveable layer, and this relief image can be contacted with a suitable functional material that is then transferred to the receiving element to provide the desired pattern.

  • Patent number: 9017927
    Abstract: A method of patterning a conductive polymer includes providing a conductive polymer layer coated over a first support followed by pattern-wise transferring a layer containing polyvinyl acetal from a second support onto the conductive polymer to form a mask with at least one opening. The masked conductive polymer is subjected to treatment through the opening that changes the conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask.

  • Patent number: 8709194
    Abstract: A method of assembling an electronic device includes providing a transparent conductive polymer layer coated over a first support followed by pattern-wise forming a transparent mask with at least one opening over the conductive polymer. The masked conductive polymer is subjected to treatment through the opening that changes conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask to form a first electronic component. The first electronic component having the mask is secured to a second electronic component, thereby forming the electronic device.

  • Patent number: 8501388
    Abstract: A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface.

  • Patent number: 6905761
    Abstract: A concentrated fine solid particle dispersion useful for forming a substantially photographically transparent magnetic recording layer is disclosed, comprising an organic solvent medium containing a dispersing agent and dispersed magnetic particles, wherein the magnetic particles are present at a concentration of at least 25% by weight and the organic solvent medium is comprised primarily of organic solvent selected from dimethyl succinate, dimethyl glutarate and dimethyl adipate. This invention provides a stable concentrated dispersion of magnetic particles useful for preparing substantially photographically transparent magnetic recording layers. A film-forming binder solution can be added to dilute the concentrated dispersion, which then can be applied to a support to form a transparent magnetic layer for a magnetic recording element.
