Manifold Imaging, Process, Composition, Or Product Patents (Class 430/40)
  • Patent number: 6873452
    Abstract: The present invention is directed to a process which comprises removing and stripping off part of the display panel in order to expose and connect the conductor lines on an electrode plate to a driver circuitry. More specifically the process involves (1) preparing a display panel having filled display cells sandwiched between a first and a second substrate layers, preferably by a roll-to-roll process; (2) removing part of a first substrate by asymmetrical cutting by, for example, a die, diamond, knife or laser cutting method to expose the layers underneath (which may include adhesive layer, primer layer, display cell layer and in the case of a display prepared by the microcup technology, the microcup layer and the sealing layer); and (3) stripping off the exposed layers by a stripping solvent or solution. After stripping, the conductor lines on the second substrate are exposed and ready for connection to the driver circuitry.

  • Patent number: 4986211
    Abstract: A toning method and member for electrostatography wherein a recording member containing information on its image bearing surface in the form of electrostatic latent images of one polarity is toned by attracting to such latent images toner material of opposite polarity including providing a carrier or toning member according to the invention containing on at least one surface thereof a dry pre-toner coating; activating such pre-toner coating with an insulative solvent to thereby solvate and confer opposite polarity to such pre-toner coating contained thereon while rendering such pre-toner coating releasable from the carrier member; establishing virtual contact between the activated and releasable pre-toner coating on the carrier member and the image bearing surface of the recording member; transferring the pre-toner coating in image configuration onto the recording member by attraction to the latent images to form toner deposits thereon; and separating the carrier member from the recording member.

  • Patent number: 4308329
    Abstract: An imaging method, and novel materials, in which there is provided an imaging mono-layer comprising a plurality of electrically photosensitive particles which comprise a resin carrier, a colorant dye, an electrically photosensitive organic material, a sensitizing dye, and a solubilizing agent for the sensitizing dye in the organic material. The imaging mono-layer is subjected to an electric field, exposed to a pattern of sensitizing electromagnetic radiation, separation of the photosensitized particles from the unsensitized particles, and color-amplification of the desired image by imbibing the colorant dye into a suitable substrate.

  • Patent number: 4187103
    Abstract: A photoconductive copy sheet suitable as an intermediate in an electrographic process, the copy sheet containing photoconductive titanium dioxide and decay retarder in the form of an organic acid or salt thereof. Preferably, the titanium dioxide is of a type having a characteristic relaxation time of less than 9 minutes whereby the copy sheet is capable of producing at least 5 and as many as 100 copies per exposure.
