Abstract

Aqueous solutions and dispersions of polyisocyanate polyaddition products containing 2 to 200 milliequivalents chemically incorporated carboxylate and/or sulfonate groups per 100 g solids and 0 to 25% by weight, based on solids, of incorporated ethylene oxide units arranged within terminal and/or lateral polyether chains, in the production of which primary and/or secondary monoamino compounds are usd, a process for their production and their use as adhesives.
