Electrophotographic material having improved protective overcoat layer.

摘要

Protective overcoat layers for electrophotographic materials are provided. Such layers comprise a polymer containing units having the structure: …… wherein:… a is 29 to 96 weight percent of the polymer;… b is 2 to 25 weight percent of the polymer; and… c is 2 to 46 weight percent of the polymer. …An especially preferred embodiment of the present invention provides an overcoat layer as described above that also includes a cross-linking agent. …The present invention encompasses an electrophotographic material comprising, in the following order:… an electrically conducting support or a support having an electrically conducting layer;… a photoconductive layer; and… an electrically insulating overcoat layer as described above.
