  • Patent number: 7005051
    Abstract: Disclosed is a three coat one bake coating process for forming an intermediate coated film, a base coated film and a clear coated film on an electrodeposition coated film. The electrodeposition coating composition is a lead-free cationic electrodeposition coating composition which has a volatile organic content of 1% by weight or less, a metal ion content of 500 ppm or less, a neutralizing acid amount of 10 to 30 mg equivalent based on 100 g of binder resin solid content. The intermediate coating composition and/or the base coated composition comprises a specific amount of a nonaqueous dispersion resin as a resin component. In the coating process, a baking step is omitted from the conventional intermediate coating process, or from the conventional base coating process.

  • Patent number: 6875471
    Abstract: The quality of painted surfaces of polymeric articles is improved by depositing a coating of a metal such as zinc or zinc alloy on the surface of the article to be painted. For example, zinc is electrodeposited on a conductive surface of the article. The metal coated polymeric surface provides a good base for electrostatic deposition of either liquid or powder paint and the metal surface prevents the formation of defects in the painted surface during heating of the article to dry or cure the paint film.

  • Patent number: 6872294
    Abstract: The quality of painted surfaces of polymer composites is improved by first forming an electroless metal coating on the molded surface of the composite and then electroplating a coating of zinc or zinc alloy on the metallized composite surface. The “galvanized” composite surface provides a good base for electrostatic deposition of either liquid or powder paint and the zinc surface prevents the formation of defects in the painted surface during heating of the composite to dry or cure the paint film.

  • Publication number: 20040241497
    Abstract: An electron beam curing resin for a magnetic recording medium is provided, wherein a known thermosetting vinyl chloride resin or polyurethane resin is modified to become sensitive to an electron beam, and the resulting resin has a high cross-linking property. A method for readily manufacturing the above-described electron beam curing resin from a known thermosetting resin is provided. Furthermore, a high-performance magnetic recording medium including the above-described electron beam curing resin is provided. The electron beam curing resin is produced through a reaction between active hydrogen groups of a vinyl chloride resin or polyurethane resin having the active hydrogen groups in a molecule and a compound having an isocyanate group and a radical-polymerizing unsaturated double bond in a molecule, wherein the amount of water in the reaction system is controlled at 0.05 to 0.5 percent by mass relative to the resin when the reaction is effected.

  • Patent number: 6818114
    Abstract: Methods for use in the production of a display include providing a substrate assembly of a face plate of the display including a conductive surface at a first side thereof. One or more projections extend from the first side of substrate assembly. A patternable material, e.g., electrophoretically depositable resist, is electrophoretically deposited on at least the conductive surface and adjacent the projections. The method may further include patterning the patternable material for use in deposition of light emitting elements on the conductive surface. Light emitting elements of one or more colors may be formed. In addition, the substrate assembly including the conductive surface may have one or more nonconductive regions formed on the conductive surface; the one or more nonconductive regions having a predetermined thickness. A layer of patternable material is formed by electrophoresis over the conductive surface and over the one or more nonconductive regions.

  • Patent number: 6779455
    Abstract: The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.
