ABSTRACT:
Aqueous polymer dispersions comprisinga) 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 fromat 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 (Tg) of the different polymers being at least 10° C., andb) 30–50% by weight of at least one polyfunctional (meth)acrylate,the dispersion a) being subjected to physical and/or chemical deodorization.
