    Abstract: A prismatic retroreflective article has a transparent body portion and a layer of internally reflecting cube-corner optical elements having an open air-exposed rear surface at least a portion of which is more hydrophobic, more oleophobic, or both more hydrophobic and more oleophobic than the underlying cube-corner optical element. The article may be made by providing a transparent body portion bearing a layer of internally reflecting open air-exposed cube-corner optical elements; treating or coating at least a portion of the cube-corner elements to make the treated or coated portion more hydrophobic, more oleophobic, or both more hydrophobic and more oleophobic than the underlying cube-corner optical elements; and leaving such treated or coated portion exposed to the open air.
