Abstract: A REMOISTENABLE ADHESIVE COMPOSITION PARTICULARLY USEFUL FOR PREPASTED WALL COVERINGS WHICH INCLUDES A DRY BLEND OF A WATER SOLUBLE LOW VISCOSITY STARCH, A LOW VISCOSITY CELLULOSE MATERIAL SUCH AS HYDROXYETHYL CELLULOSE, CARBOXYMETHYL CELLULOSE OR METHYL CELLULOSE ETHER, AND A PLASTICIZER SUCH AS SODIUM NITRATE, UREA, CALCIUM CHLORIDE, GLYCERIN OR SODIUM METHACRYLATE. THE ABOVE BLEND MAY ALSO INCLUDE AN EXTENDER MATERIAL SUCH AS SODIUM METHACRYLATE OR A CLAY, OR BOTH IN COMBINATION. THE ADHESIVE IS NOT DISTURBED BY FURTHER HANDLING AND CAN BE APPLIED TO THE WALL COVERING EITHER BEFORE OR AFTER PRINTING THE DECORATIVE SURFACE. THE WALL COVERINGS TREATED WITH THIS ADHESIVE ARE EASILY APPLIED WHEN REMOISTENED, BECAUSE THEY HAVE GOOD "SLIP" PROPERTIES. THEY ARE ALSO EASILY REMOVED AFTER INSTALLATION WITHOUT THE USE OF STEAM OR OTHER STRIPPING AGENTS, SIMPLY BY PULLING THE COVERING AWAY FROM THE UNDERSURFACE.
