Abstract

Polyvinyl formal resin is used as a binder in a photoconductor system, such as an organic system of 2,4,7-trinitro-9-fluorenone (TNF), and poly-n-vinylcarbazole (PVK). A particularly advantageous polyvinyl formal resin is FORMVAR* 15/95S. The use of polyvinyl formal resins increases light sensitivity, enhances flexibility, reduces effects of cycling fatigue (light and dark), and allows use of what would otherwise be unacceptable TNF and PVK. * Trademark of Monsanto Co.
