Aqueous dispersion, production process therefor, water-based coating material, and coated article

Provided are: an aqueous dispersion capable of giving a water-based coating material which is excellent in terms of coloration stability and pH stability and has highly stable thixotropic properties;a process for producing the aqueous dispersion; a water-based coating material; and a coated article. The aqueous dispersion comprises an aqueous medium and, dispersed therein, a fluoropolymer comprising units based on a fluoroolefin and units based on a monomer having a crosslinkable group, and contains at least one ingredient selected from the group consisting of persulfuric acid salts and products of decomposition thereof, the content of the ingredient being 0.01-0.22 mmol in terms of persulfuric acid salt amount per 100 g of the fluoropolymer. 提供可得到着色稳定性及pH稳定性优异、并且触变性的稳定性优异的水性涂料的水性分散液、其制造方法、水性涂料及涂装物品。种水性分散液，其是含氟聚合物分散于水性介质而成的水性分散液，所述含氟聚合物具有：基于氟烯烃的单元及基于具有交联性基团的单体的单元，所述水性分散液包含选自由过硫酸盐及其分解产物组成的组中的至少1种成分，该成分的含量相对于含氟聚合物100g以过硫酸盐换算计为0.01～0.22mmol。
