Abstract
The present invention relates to an imaging element comprising an imaging layer and a support, wherein the support comprises a core layer having a surface roughness of at least 1.4 microns and a pit camouflaging flange layer between the support and the imaging layer. The present invention also relates to a method of forming an imaging support comprising extruding a polymer layer onto a core layer of surface roughness of at least 1.4 microns, and passing the extruded polymer layer on the core layer between two temperature controlled rollers, one of which comprises a pit camouflaging surface and a method of forming an imaging support comprising extruding a polymer layer, passing the extruded polymer layer between two temperature controlled rollers, one of which comprises a pit camouflaging surface, and laminating the polymer layer onto a core layer with a surface roughness of at least 1.4 microns.
