Abstract: An ink for a display panel that at a time of application is a mixture of a powder material, a water-soluble resin included in a range of 1 wt % to 20 wt % inclusive of the ink, and a water-miscible solvent. The ink is water-soluble, and in comparison to conventional organic inks, the ink of the present invention exhibits a markedly reduced susceptibility to the occurrence of electrostatic action.

Abstract: A self-assembly process for preparing luminescent organic-inorganic nanocomposite thin films is disclosed. A homogeneous solution in water and an organic solvent is obtained containing a soluble silicate, a silica coupling agent, a surfactant, and an organic material having a hole transport, electron transport, and/or emissive material moiety.

Continued evaporation promotes self-assembly of the micelles into interfacially organized liquid crystalline mesophases. Reacting the organic material and silica coupling forms a nanostructure self-assembly.

The highly specific excitation and emission rates, coupled with a high inverse contrast on papers of all colors, makes them particularly useful as ink jet inks for postal and other purposes.
