Abstract
There is provided an article comprising at least a first surface having a fluorine-containing polymeric binder resin layer and a plurality of microspheres partially embedded in a first major surface of the binder resin layer and adhered thereto; wherein the fluorine-containing polymer is derived in part from at least one partially fluorinated, or non-fluorinated, monomer; and wherein the article exhibits a stain resistance to yellow mustard at elevated temperature and humidity as measured by the change in b* of less than 50. There are also provided such articles wherein the fluorine-containing polymer is derived in part from at least one partially fluorinated, or non-fluorinated, monomer; and wherein the fluorine content along the polymeric backbone of the fluorine-containing polymer is from about 27% to 72% by weight. There are also provided such articles wherein the article is a thermoformable article exhibiting chemical resistance according to ASTM D5402-06.
