Abstract: Aqueous polymer dispersions comprising a) 50-70% by weight of polymer particles composed of at least two different (co)polymers having glass transition temperatures each above 50° C. and synthesized from at least 80% by weight of at least one principal monomer, 0.1-10% by weight of at least one auxiliary monomer, and 0-3% by weight of at least one crosslinker molecule, the difference in the glass transition temperatures (T g ) of the different polymers being at least 10° C., and b) 30-50% by weight of at least one polyfunctional (meth)acrylate, the dispersion a) being subjected to physical and/or chemical deodorization.
