Abstract

Binders and coatings, which give water-resistant films on drying are made by reacting undergraded starch with an hydrolytic enzyme, followed by introduction of glyoxal into the reaction medium. The undergraded starch in aqueous suspension, may be heated with 0.1 to 2% of enzyme e.g. a diastase or amylase, to yield an aqueous solution of pH 4 to 7, to which is added 2-50% of glyoxal, based on the initial weight of starch. The glyoxal may be added in solution or in solid form. A surfacing paste for printing on wallpaper comprises the above starch mixed with water, chalk, sodium polyacrylate, vinyl acrylic copolymer latex and a deflocculant; and may also contain kaolin.
