Estimating the term…
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.
An imaging element comprising at least one imaging layer and a support, wherein said support comprises a layer having a surface roughness of at least 1.4 microns and at least one pit camouflaging flange layer between said support and said imaging layer, wherein the spatial frequency of surface features, having peak to valley heights in the range from 1.1 to 3.4 microns, in said pit camouflaging flange layer is from 0.01 mm to 10 mm and wherein said imaging element has a surface roughness of less than 1.1 μm.
