Abstract
Electrophotographic compositions containing zinc oxide dispersed in a certain resin binder mixture and sensitized with a cyanine dye having a particular structure provide high sensitivity in the 780-840 nm wavelength range, excellent thermal stability, long dark decay time and near-white appearance. The compositions are particularly useful for non-transfer electrophotography and for electrostatic printing applications.
