Abstract: The invention relates to a concentrated aqueous polymer dispersion with an average particle size of less than 1000 nm comprising g) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of h) a non-polar photoinitiator and/or photolatent catalyst and i) optionally a non-ionic, cationic or anionic surfactant, wherein the weight ratio of the non-polar photoinitiator and/or photolatent catalyst to the polymer carrier is greater than 20 parts of photoinitiator and/or photolatent catalyst per 100 parts of polymer carrier.
