    Abstract: The preservation method of microcapsules for electrophoretic display devices according to the present invention includes preserving microcapsules for electrophoretic display devices in a water-based medium having an electric conductivity of 500 ?S/cm or lower. The preservation under such conditions makes it possible to preserve microcapsules for electrophoretic display devices over a long period of time without deteriorating their electrophoretic properties. The microcapsules for electrophoretic display devices, which have been preserved by the preservation method of the present invention, can be used, as its applications, for sheets for electrophoretic display devices and electrophoretic display devices using the sheets.

  • Patent number: 7357884
    Abstract: A conductive ink composition is obtained by dispersing, in an organic solvent, a solid material made from metal fine particles each coated with protective colloids each made of at least two organic compounds, the metal fine particles consisting of an alloy containing at least a noble metal. Each of the protective colloids is made from, e.g., a raw material containing an (A) amine and a (B) carboxylic acid. By applying and baking the conductive ink composition, grain growth is restrained. This allows acquirement of a metal film whose surface smoothness is excellent, and whose adhesiveness to an application target is improved as compared with that of a metal film made from a conventional conductive ink composition.

    Abstract: A polymer compound having a functional group containing a cyclic part with aromatic properties comprising C, H and/or C, H, X (X is a hetero atom) in the side-chain, and a number average molecular weight of 250-1,000,000. The molar optical absorption due to the cyclic part with aromatic properties of the polymer compound is lower 30% or more than the molar optical absorption due to the cyclic part with aromatic properties in a polymerizing monomer used to introduce the cyclic part with aromatic properties. As this cyclic part has an overlapping stack structure, the compound has a hypochromic effect, and if an electron donor compound or electron-accepting compound is added, a charge transfer complex is formed.
