    Abstract: An object of the present invention is to provide an aqueous dispersion capable of forming a coating film excellent in water resistance, antifogging properties and durable light resistance, a method for producing the aqueous dispersion, an aqueous coating material, and a coated article. This aqueous dispersion comprises water, a surfactant and polymer particles dispersed in the water, wherein the polymer particles contained in the aqueous dispersion are fluoropolymer particles and (meth)acrylate polymer particles, or polymer particles comprising a fluoropolymer and a (meth)acrylate polymer; the fluoropolymer contains units based on a fluoroolefin in an amount of from 95 to 100 mol % to all units which the fluoropolymer comprises; the (meth)acrylate polymer contains units based on an alkyl(meth)acrylate in an amount of from 75 to 100 mol % to all units which the (meth)acrylate polymer comprises; and the surfactant is a compound of such a structure that to a benzene ring, 1 group represented by the formula —(OQ)nOSO3−X+ (where Q is an alkylene group, n is an integer of from 2 to 48, and X+ is Na+ or NH4+) and 2 to 4 phenylalkyl groups are bonded. A method for producing the aqueous dispersion is also provided.
