ABSTRACT:
The invention relates to aqueous adhesives which are based on water-dispersible polymers and which contain water-dispersible polyisocyanate preparations having an average NCO-functionality of at least 2.2, which, in addition to an aromatic polyisocyanate or a mixture of aromatic polyisocyanates, contain a quantity of emulsifier sufficient to guarantee the dispersibility of the polyisocyanates, as additives capable of improving the bonding properties of these adhesives.
