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.
An imaging element comprising an imaging layer and a base, wherein said base comprises an integral polymer sheet having an oriented polymer core of insufficient stiffness for an imaging base and at least one unoriented polymer stiffening layer, wherein said unoriented polymer stiffening layer is of a higher modulus than said oriented polymer core.
An imaging element comprising an imaging layer and a base, wherein said base comprises at least one integral polymer sheet comprising a voided oriented polymer core of insufficient stiffness for an imaging base between at least one nonvoided unoriented polymer upper stiffening layer and at least one nonvoided unoriented polymer lower stiffening layer, wherein said unoriented polymer stiffening layer is of a higher modulus than said oriented polymer core.
A process of manufacturing a base for an imaging element comprising the steps of:
