| description | 1,156,822. Electro-photographic. GEVAERTAGFA N.V. June 24, 1966 [June 25, 1965 (2); April 14, 1966], Nos. 16459/66; 27725/66 and 27726/66. Heading G2H. [Also in Division H1] Electro-photographic images are prepared by imagewise irradiating a non-precharged electrophotographic material comprising an n-type photoconductor (e.g. ZnO or TiO 2 ) mixed with a substance (preferably a hydrophilic polymer) containing at least one chemical group which accepts electrons from the irradiated photo-conductor and developing the image thus formed, preferably using an electro-phoretic liquid developer (e. g. carbon black in a hydrocarbon). The exposure may be effected using X-rays, or white, U.V. or incandescent light. The electro-photographic material preferably also contains cations, a dispersing agent and a compound which increases the dark-resistivity of the photo-conductor, (see Division H1). |
