The photoconductors used in photocopiers often consist of a layered organic medium coated onto an aluminized polymer substrate. The photoconductors usually consist of at least three layers. The binder layer provides for proper adhesion of the charge-generation layer (CGL) to the aluminum substrate; the CGL contains a dye that generates electron-hole pairs when exposed to light of the proper wavelength; the charge transport layer contains a material imbedded in a polymeric matrix for the transport of holes from the CGL to the surface of the photoconductor. Organic layered photoconductors are prepared by conventional coating processes whereby heat is used to drive off solvents from an uncured film. This process is expensive. We describe a process for preparing a CGL that uses no solvents and requires only one step.
