ABSTRACT:
The present invention relates to an imaging member comprising an imaging layer and a base wherein said base comprises a polymer sheet having at least one oriented polymer core and adhered thereto at least one unoriented polymer layer. Another embodiment relates to an imaging element comprising an imaging layer and a base, wherein said base comprises an integral polymer sheet having at least one oriented polymer core and at least one unoriented polymer layer. The invention further relates to a process of manufacturing a base for an imaging element comprising the steps of extruding a voided core polymer sheet; orienting said extruded voided core polymer sheet; and extrusion coating said oriented extruded voided core polymer sheet with at least one unoriented polymer layer.
