AQUEOUS POLYMER DISPERSIONS FOR TRANSPARENT LACQUERS

摘要

An aqueous polymer dispersion based on polyester and acrylate is obtained by radical polymerisation of at least (a) one (meth)acrylic acid ester and (b) one ethylenically unsaturated, at least monofunctional acid and if required (c) one ethylenically unsaturated monomer different from (a) and (b), or mixtures thereof, with a radically polymerisable polyester resin. Also disclosed is a process for producing said aqueous polymer dispersions, aqueous transparent lacquers containing these aqueous polymer dispersions and their use.
