Abstract: The present inventions relates to an aqueous multi-stage copolymer dispersion, particularly an aqueous multi-stage copolymer dispersion useful for paints which need water whitening resistance, wherein the multi-stage copolymer consisting of a first stage copolymer having a Fox Tg in the range of -10 to 20º C resulted from first stage monomers and a second stage copolymer having a Fox Tg in the range of 60 to 120º C resulted from second stage monomers, and relates to a paint comprising the aqueous multi-stage copolymer dispersion.
