Visible Imaging Using Radiation Only Other Than Heating By Surface Contact Or Convection Patents (Class 430/346)
  • Patent number: 4199615
    Abstract: A dry-process imaging film which is sensitive to, and substantially simultaneously imaged and developed by, electromagnetic radiation above a threshold value applied thereto through an imaging mask. The film, in its preferred form, comprises a thin solid continuous, non-particulate film of a dispersion imaging material provided with a thin, flexible, protective overlayer of a polymeric resin. The film of dispersion imaging material is carried or supported on a flexible plastic substrate which may be transparent or light reflective.
