  • Publication number: 20100036060
    Abstract: Ion-conducting (co)polymer media and ion-conducting oligomer media close in ion conductivity to organic-solvent-based electrolytes can be produced easily and safely on industrial scale. These ion-conducting (co)polymer media use (co)polymers containing at least one cyclocarbonato group, and these ion-conducting oligomer media employ oligomers containing at least two cyclocarbonato groups.

  • Patent number: 7368148
    Abstract: Color filters can each be fabricated by printing a pixel pattern for the color filter on a flexible plastic film by a central impression cylinder press. The pixel pattern is formed of pixels of three primary colors consisting of red, green and blue or pixels of three primary colors consisting of yellow, magenta and cyan. Also disclosed are inks, color filters, and image displays using the color filters.
