<p>A charge receptor film element for charge transfer imaging comprising, in order, (a) support, e.g., transparent film, (b) conductive layer, e.g., metal, metal oxide, ammonium chloride salt, (c) thin dielectric layer bearing, e.g., transparent polyethylene terephthalate, (d) opaque dots, e.g., 3 to 50 micrometers in height, covering less than 10% of the total area of layer (c) which provide less than 0.05 background optical density. The element is useful for medical radiography, in eletrophotography, electrostatic printing, etc.</p> |
