Zusammenfassung:	A composition comprises an aqueous dispersion of polymer particles, polymeric organic crosslinked microspheres, and colloidal silica particles. The composition is useful in coating compositions for exterior applications to achieve a balance of excellent dirt pickup resistance and durability performance under accelerated testing conditions. Une composition comprend une dispersion aqueuse de particules de polymères, des microsphères polymères réticulées organiques et des particules de silice colloïdale. La composition est utile dans des compositions de revêtement pour des applications extérieures en vue d'obtenir un équilibre entre une excellente résistance à la rétention de salissures et d'excellentes performances de durabilité dans des conditions de test accélérées.
