Abstract
The invention relates to aqueous adhesive dispersions containing A) 0.1-10 wt. % adhesive polymer in the form of a dispersion with respect to the overall weight of the dispersion, B) 0.1-100 parts by weight of constituent A), an anionic or cationic polyelectrolyte and C) 0-50 parts by weight in relation to the 100 parts by weight of constituents A) of at least one polyalkyleneglycol with a molar mass of 200-100,000 g/mol. The invention also relates to the use of said dispersions in the production of multi-layered paper or paper material.
