Abstract
Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer, a transparent magnetic layer comprising magnetic particles dispersed in a film-forming binder and a transparent electrically-conductive layer comprising a sputter-deposited layer of a metal oxide. Use of a sputter-deposited metal oxide provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.
