FIELD: adhesives.
SUBSTANCE: invention relates to aqueous starch-containing adhesive compositions, in particular starch-based adhesives for gluing paper products. Proposed aqueous adhesive composition contains a starch derivative and clay. Starch derivative is a highly branched starch (HBS), obtained by treating starch or starch derivatives with a branching glycogen enzyme (EU 2.4.1.18). Weight ratio of the specified highly branched starch to the specified clay is in the range from about 1:1 to 1:4. Method is also proposed for gluing two substrates using said adhesive composition and using the obtained glued product as a paper product of the class, suitable for contact with food, packaging for confectionery, pharmaceutical and cosmetic products and products for personal hygiene.
EFFECT: resulting adhesive composition has a high adhesiveness and setting speed when gluing and does not contain boron.
