Abstract
Electrophotographic papers comprising electrically conducting paper supports and photoconductive insulating compositions in the form of organic photoconductive dispersions are described. Particles of certain polyphenyl organic photoconductors with para-linked phenyl groups, or polyarylated unsaturated organic photoconductors are dispersed in cellulose nitrate to provide useful photoconductive insulating dispersions.
