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.
Claims31
A method of imaging comprising:
- a. providing an imaging mono-layer comprising a plurality of electrically photosensitive particles made of a resin carrier, a colorant dye, and an electrically photosensitive organic material, said organic material being sensitized by a sensitizing dye and a solubilizing agent for said sensitizing dye, said resin carrier comprising two components:
- a first component substantially surrounding said colorant dye, said first component being selected to prevent photosensitization of said particles by said colorant dye during the exposure step;
- and a second component substantially surrounding said first component and the colorant dye, said second component being selected to facilitate the photosensitization of said particles by said organic material,
- b. applying an electric field across said imaging mono-layer;
- c. exposing the imaging mono-layer to a pattern of electromagnetic radiation to which said mono-layer is sensitive;
- d. separating the photosensitized particles from the unsensitized particles during the application of said electric field so that a positive image and a negative image are formed corresponding to the original pattern;
- and
- e. fixing at least one of said images onto a substrate.
An imaging member comprising a mono-layer sandwiched between a donor member and a receiver member, at least one of said members being at least partially transparent to electromagnetic radiation to which said mono-layer is sensitive, said mono-layer comprising a plurality of electrically photosensitive particles made of a resin carrier, a colorant dye, and an electrically photosensitive organic material spectrally sensitized with a sensitizing dye and a solubilizing agent for said sensitizing dye, said resin carrier comprising two components:
- a first component substantially surrounding said colorant dye, said first component being selected to prevent photosensitization of said particles by said colorant dye during the exposure of said imaging member;
- and a second component substantially surrounding said first component and the colorant dye, said second component being selected to facilitate the photosensitization of said particles by said organic material.
An electrically photosensitive material comprising a mixture of photosensitive organic material, a sensitizing dye, and a solubilizing agent for the sensitizing dye, said solubilizing agent is polyethylene glycol, polycaprolactone, polycaprolactone diol, or N-vinyl carbazole.
