    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.

    Abstract: Aqueous starch paste is acid converted to a hydrolyzate having a dextrose equivalent constant (D.E.) in the range of from about 8 to about 16 percent, then after removal of any insoluble fatty material present, the acid hydrolyzate is cooled for at least 1 hour at a temperature below about 60* F., e.g., in the range of from about 32* F. to about 50* F., and precipitated material formed then is separated from the chilled hydrolyzate liquor. The resultant hydrolyzates, as well as hydrolyzates formed by slight alpha-amylase conversion of the resultant liquor, form aqueous syrups having excellent stability against haze formation. The lower D.E. hydrolyzates produced also are essentially nonsweet and nonhygroscopic.
