ABSTRACT:
An electroconductive imaging element, that is especially useful in a high speed laser printing process utilizing electrostatography, is comprised of an insulating support, an electrically-conductive layer overlying the support and a thermoplastic dielectric imaging layer overlying the electrically-conductive layer. The electrically-conductive layer, which is comprised of at least 3 milligrams per square meter of a colloidal gel of vanadium pentoxide dispersed in a polymeric binder combines a high degree of transparency with a high degree of electrical conductivity. The thermoplastic dielectric imaging layer has a thickness of at least 0.2 micrometers and a surface resistivity of at least 10.sup.13 ohms/square and is comprised of a thermoplastic polymer with a glass transition temperature of at least 20.degree. C.
