摘要:
Water-soluble or water-dispersible addition copolymer of ethylenically unsaturated monomers, wherein the ethylenically unsaturated monomers comprise N-vinyl-2-pyrrolidinone and ethylenically unsaturated polyether, is useful as a component of inkjet printable coatings. The copolymer serves to reduce later migration of inks printed on the coatings.
摘要:
Describes a composition for producing durable coatings and a process for preparing a single-layer broad band antireflective coating on solid substrates, such as glass, ceramics, metals, and organic polymeric materials. The coating composition comprises, in combination, acid catalyzed hydrolysis and condensation products of water-silane monomer mixture and a film forming amount of a polymer having functional groups selected from amino, hydroxy and carboxy, hydroxy and amino, amino and carboxy, and amino, hydroxy and carboxy. The described process comprises applying the aforesaid coating composition (or an acid catalyzed sol-gel coating composition) substantially free of preformed oxide sol and water soluble metal salt to the surface of a solid substrate, curing the applied coating, and treating the cured coating with an aqueous electrolyte solution for a time sufficient to produce a coating having graded porosity which is antireflective over a broad band of the visible spectrum.

The invention is directed to conductive polymer compositions, catalytic ink compositions (e.g., for use in screen-printing), electrodes produced by deposition of an ink composition, as well as methods of making, and methods of using such compositions and electrodes. An exemplary ink material comprises a metal catalyst (e.g., platinum black and/or platinum-on-carbon), graphite as a conducting material, a polymer binding material, and an organic solvent. In one aspect, the polymer binding material comprises a polymer binder blend comprising first and second polymers, wherein the first polymer has a glass transition temperature higher than the second polymer. In a second aspect, the polymer binding material comprises a hydrophilic acrylic polymer, copolymer, or terpolymer. The conductive polymer compositions of the present invention may be used, for example, to make electrochemical sensors. Such sensors may be used, for example, in a variety of devices to monitor analyte amount or concentrations in subjects.

摘要:
This invention relates to a two layers or more anti-static film coating deposited on a substrate. Selected layers of the films may have anti-static and/or electromagnetic properties. In one embodiment, the film farthest from the substrate has an index of refraction lower than the underlying film. In another embodiment, the surface of the film is roughened to provide a graded index of refraction.
