IMAGING MATERIALS COMPRISING ELECTRICALLY CONDUCTIVE POLYMER PARTICLE LAYERS

摘要

Image-forming materials including photographic, thermographic, and thermally-developable imaging materials include one or more transparent electrically conductive, non-charging layers to provide antistatic control on one or both sides of subbed or unsubbed supports. The electrically conductive, non-charging layers comprise colloidal, electrically conductive polymer particles that can be dispersed in a film-forming binder in an amount to provide from about 10 to about 90 volume % of polymer particles. Particularly useful polymer particles include pyrrole-containing, thiophene-containing, and aniline-containing polymers. The particles generally exhibit a packed powder specific resistivity of 10<5> ohm-cm or less and generally have a mean diameter of 0.5 mu m; or less. The electrically conductive, non-charging layers generally exhibit a surface electrical resistivity of less than 1 x 10<12> ohm per square.
