-20- Abstract of the Disclosure Re-usable sheet material, having a dark colored base sheet provided on each side with a microvoid layer, temporarily imageable by application of volatile liquids, is treated on the face side with oleophobic (preferably also hydrophobic) fluorochemicals. Surface contamination of the face side with oil, which would cause permanent transparentization and prevent re-use, is readily removed by placing the face side of the sheet material in contact with the back side. One use for the product is as an order blank in the fast food industry.
