  • Patent number: 8053147
    Abstract: High performance media suitable for recording with a blue laser is disclosed. The blue-sensitized holographic media provides greater dynamic range and higher sensitivity than previously disclosed blue-sensitized holographic media. These media can be used for diverse applications such as data storage where the articles provide denser data storage and more rapid hologram writing times or for optical waveguides where the articles provide greater optical confinement and more rapid manufacturing times.

  • Patent number: 7736818
    Abstract: A laminated holographic recording medium having (a) a first substrate having a through-hole and (b) a solid polymer matrix layer that records holographic data laminated to the first substrate and a method of manufacturing thereof are disclosed.

  • Patent number: 7282322
    Abstract: A novel photoimageable system for a two-chemistry system containing liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and an aluminum salt compound is disclosed. The photoimageable system has high dynamic range (M/#) and sensitivity and unexpectedly high temperature and high humidity resistance. The photoimageable system retains its dynamic range when exposed to 60° C. for 4 weeks while a composition without the aluminum salt compound lost 75% of its dynamic range under similar exposure conditions. In one embodiment, 2-10 weight % of a thio-butylacrylate dissolved in a two-component urethane matrix containing 0.002 to 1 weight % of the aluminum salt compound showed a dynamic range of greater than 5 for a 200 microns thick sample and retained more than 80% of the dynamic range after 4 weeks exposure at 60° C.

  • Patent number: 7229741
    Abstract: A novel liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and having high dynamic range sensitivity is disclosed. The acrylate compound is a monomer for a photoimageable system. In one embodiment, when about 2–8% by weight of the acrylate compound is dissolved in a two-component urethane matrix system and incorporated in an optical article formed by reacting the two-component urethane matrix system, the optical article shows a sensitivity of about 4 or more and a shrinkage during the formation of the optical article of about 0.05% versus a sensitivity of 2.26 and a shrinkage of 0.13% when tribromophenyl acrylate, a commercial monomer, was used.

  • Patent number: 6765061
    Abstract: Holographic articles having self-sealing properties such as moisture resistance and environmental durability are disclosed. The holographic articles are formed by the reaction of a composition containing an excess amount (i.e. non-stoichiometric amount) of polyisocyanates to polyols. The holographic recording articles exhibit high optical clarity and low scattering.

  • Patent number: 6743552
    Abstract: A rapid mass production of the high performance holographic recording articles including the process and composition are described. To prepare a high performance holographic recording article based on two-component urethane matrix system, for example, polyols and all the additives must be virtually free of moisture contents. Deaeration must be carried out, once isocyanate and polyols including catalysts and all other ingredients are mixed together, to eliminate all entrapped air that is introduced into the mixture during mixing. The deaeration takes time, and the urethane reaction must not be allowed to take place until all air bubbles are evacuated from the isocyanate-polyols mixture. The rapid mass production of this invention overcomes such process limitations and results in a high-volume production of the high performance holographic recording articles.

  • Patent number: 5891582
    Abstract: A resin composition comprises an acrylated polyester, the polyester being the reaction product of an equivalent excess of 1,6-hexanediol and an aromatic polycarboxylic acid or anhydride, preferably trimellitic anhydride. In the preferred embodiment, the reaction product includes a highly ethoxylated triacrylate. Upon UV initiated polymerization or copolymerization, improved clear coatings for "no-wax" resilient floors are obtained. These coatings have better resistance to household and other stains than commercial urethane/acrylate floor coverings.
