The present invention relates to an aqueous emulsion comprising a dispersant of a modified polyvinyl alcohol with an ethylene unit content of 2 to 9 mol% and a degree of hydrolysis of at least 95 mol%, a dispersoid of a polymer of an ethylenically unsaturated monomer, and a ratio (?2rpm/?20rpm) of Brookfield viscosity at 30°C, 2 rpm (?2rpm) as against Brookfield viscosity at 30°C, 20 rpm (?20rpm) being 1 to 1.8 when the latter viscosity (?20rpm) is adjusted to 5,000 to 10,000 mPaS. The aqueous emulsion according to the present invention is excellent in structural viscosity (flowability, high speed application performance), provides coated layers with high water resistance and low- temperature stability, and can be suitably used extensively as an adhesive for paper, wood and plastics, as a binder for impregnated paper and non-woven products, as an additive for mortar, as a paint, and in paper and fiber processings.
