Abstract
Photoconductive insulating compositions comprising organic photoconductors are described. Organic photoconductor materials such as p-terphenyl or polyvinylcarbazole are dispersed or dissolved in an electrically insulating binder and chemically sensitized with a polymer having repeating units to which are appended a monovalent chlorendate radical. When employing the aforesaid polymeric chemical sensitizer, acrylic polymers or cellulose nitrates are especially useful as insulating binders for heterogeneous compositions of the subject type. Or, by omitting conventional binders, the described polymeric chemical sensitizer can function simultaneously as chemical sensitizer and insulating binder for such photoconductive compositions. Further, the present polymeric chemical sensitizer is particularly useful with one or more additional chemical sensitizers to yield sensitized compositions with especially desirable properties. Compositions comprising the polymeric chemical sensitizers of this invention are applied to an electrically conducting support to prepare electrophotographic elements.
