摘要： The present invention is a composition comprising a stable aqueous dispersion of polymer particles and a sorbate ester, which is a liquid at 20° C. and has a molecular weight in the range of 125 to 500 g/mol. The composition of the present invention provides a way to enhance film formation of coatings prepared using relatively high Tg latexes without the aid of high volatile organic content (VOC) coalescents.
