Abstract
309,019. Wolff & Co., and Weingand, R. April 3, 1928, [Convention date]. Addition to 304,722. Compound sheet materials.-Composite material as described in the parent Specification is made by uniting cellulose foils obtained from viscose or other aqueous solutions of regenerated cellulose and cellulose ester foils which do not swell in water by means of a solution of an albuminoid in a solvent adapted to dissolve the cellulose ester. The albuminoid is preferably gelatine and the solvent glacial acetic acid. The albuminoid may be subsequently hardened with formaldehyde or aluminium sulphate. A softening agent such as camphor may be added to the adhesive solution. In a modification, the cellulose foil may be replaced by foil of cellulose derivatives which swell in water.
