Abstract

966,436. Electrophotographic materials. BELL & HOWELL CO. Oct. 15, 1962, No. 38951/62. Drawings to Specification. Heading H1K. A photoconductive layer for use in electrophotography is produced by dispersing a particulate photo-conductor with a resinous binder in a solvent and coating the mixture on to a smooth highly polished surface upon which it is dried to form a photo-conductor layer which may be readily peeled from the casting surface and which thus has one smooth, very flat face having a higher and more uniform particle density than the remainder of the film and suitable for the production of high resolution images. Suitable photo-conductors include selenium and zinc oxide and other organic and inorganic materials such as oxides, sulphides, selenides, tellurides and tungstates, in particular : zinc sulphide, zinc-magnesium oxide, cadmium sulphide, zinc silicate, cadmium selenide, mercuric iodide, mercury oxide, mercuric sulphide, indium trisulphide, arsenic sulphide, asenic selenide, antimony trisulphide, and lea d oxide. In the particular embodiments zinc oxide is used. The examples given of smooth highly polished casting surfaces are glass, aluminium, stainless steel, chromium and polyethylene terephthalate sheet. Binders used in the-examples are polyvinyl chloride-acetate, silicone resins, polyvinyl butyral resins, and epoxy resins. In five of the examples, rose bengal, methylene blue, fluorescein, acridine orange, and eosin yellow are respectively used as sensitizers. In most cases the photoconductive layer is further dried or " cured " after removal from the casting surface on which the initial drying takes place. The layer may be used as a self-supporting film, or supporting materials such as gummed paper or gummed aluminium foil may be stuck to the rougher (free) face of the film before it is separated from the casting surface. A continuous coating apparatus is described with reference to Fig. 3 (not shown), which produces a porous-paper supported film. Other supporting materials described which are applied as an overcoat before separating the photo-conductive layer from the casting surface are polyvinyl butyral, carboxymethyl cellulose, methocel, polyvinyl chloride, polyvinyl chloride-acetate, polyvinyl acetate, cellulose acetate butyrate, and cellulose acetate. Plasticizers and conducting additives may be added to these overcoating layers and it is stated that photoconductive material may also be present but to a lesser extent than in the true photoconductive layer.
