  • Patent number: 7722958
    Abstract: Provided is a film-forming composition substantially free of organic solvent which includes an aqueous dispersion of polymeric microparticles prepared by emulsion polymerization of a monomeric composition containing (1) at least 10 percent by weight of one or more vinyl aromatic compounds; (2) 0.1 to 10 percent by weight of one or more carboxylic acid functional polymerizable, ethylenically unsaturated monomers; (3) 0 to 10 percent by weight of one or more polymerizable monomers having one or more functional groups capable of reacting to form crosslinks; and (4) one or more polymerizable ethylenically unsaturated monomers. Each of (1), (2), (3) and (4) are different one from the other and at least one of (3) and (4) is present in the monomeric composition. Multi-layer composite coatings and coated substrates also are provided.

  • Publication number: 20090208648
    Abstract: A process for producing an article having modified optical, chemical, and/or physical properties is disclosed. The process includes (a) fluidizing a starting material; (b) forcing the fluidized starting material toward the article; and (c) passing the fluidized starting material through a high energy zone. The passing step can occur before the forcing step; after the forcing step but before the fluidizing material comes in contact with the surface of the article; and/or after the forcing step and after the fluidized material comes in contact with the surface of the article. The properties of the article are modified because the article has nano-scaled structures distributed on the surface of the article and/or at least partially embedded in the article.

  • Publication number: 20070293618
    Abstract: A curable powder film-forming composition is provided, comprising (i) 5 to 95 percent by weight of a crosslinking agent; (ii) 5 to 95 percent by weight of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) particles having a mean particle size less than 100 nm. The particles comprise 10 to 70 percent by weight aluminum oxide and 30 to 90 percent by weight silica, and are substantially free of functional groups on the particle surface. The particles are present in an amount sufficient to improve the flow and leveling of the composition when applied to a substrate and cured, compared to a similar cured coating without the particles. A multi-component composite coating composition is also provided, comprising a pigmented basecoat and a clear coat. The basecoat and/or clearcoat may be derived from the curable film-forming composition described above.

  • Publication number: 20070165976
    Abstract: The present invention discloses a display panel 10 having a substrate 12 with one or more surfaces and one or more features 30 within the substrate 12. When one or more surfaces of the substrate 12 are illuminated, the features 30 redirect the illumination to form an image.

  • Publication number: 20050249939
    Abstract: Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the coating as compared to a coating where no particles are present. Also, the difference between the refractive ranges from 1 to 1.5. A method for preparing a powder coating including the particles also is provided.
