  • Publication number: 20050191568
    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.

  • Publication number: 20050112352
    Abstract: A single or multilayer sheet comprising a microvoided layer permeable to low surface tension liquids has a continuous phase comprising a polylactic-acid-based material and interconnecting microvoids, said microvoided layer having a total absorbent capacity of at least about 14 cc/m2. The invention is also directed to an a method of making a sheet material comprising such a permeable microvoided layer, which method comprises extruding a sheet comprising a layer of a polylactic-acid-based material containing inorganic particles by extrusion, and stretching the sheet biaxially to form interconnected microvoids around the inorganic particles.
