    摘要： The present invention relates to an imaging member comprising an imaging layer and at least one stiffening layer comprising a blend of polyolefin polymer and amorphous hydrocarbon resin. The invention further describes a method for making the imaging member, comprising extruding a foam polymer sheet, orienting the foam polymer sheet, bringing a stiffening layer comprising a blend of polyolefin polymer and amorphous hydrocarbon resin into contact with the oriented foam polymer sheet, and applying an imaging layer above the stiffening layer. A second method of forming an imaging member comprises extruding a foam polymer sheet, bringing at least one stiffening layer comprising a blend of polyolefin polymer and amorphous hydrocarbon resin into contact with the foam polymer sheet, orienting said foam polymer sheet and said stiffening layer and applying an imaging layer above said stiffening layer. Another method describes the formation of an imaging member comprising making a cellulosic sheet, bringing at least one stiffening layer comprising a blend of polyolefin polymer and amorphous hydrocarbon resin into contact with the cellulosic sheet and applying an imaging layer above the stiffening layer.

    摘要： The invention relates to an imaging element comprising an imaging layer and a support, wherein the support comprises a base material having thereon at least two polyolefin layers, wherein the uppermost layer of the at least two polyolefin layers comprises a mixture of optical brighteners comprising a Compound A having the following formula: a Compound B having the following formula: and a Compound C having the following formula: wherein the layers below the uppermost layer of the at least two polyolefin layers comprise migratory optical brightener; and wherein the imaging layer is on the same side of the base material as the at least two polyolefin layers. The inventive support unexpectedly minimizes exudation of the brightener at the polyolefin surface and provides excellent absorption/emission characteristics, brightening power and heat to meet the critical requirements of the photographic field.
