Abstract
The present invention provides an aqueous fluoropolymer dispersion that shows favorable dispersion stability and is less likely to have a pH decrease even after storage for a long period of time. The present invention provides an aqueous fluoropolymer dispersion including: a fluoropolymer; a fluorine free surfactant; at least one organic electrolyte selected from the group consisting of hydroxy monocarboxylic acids, hydroxy dicarboxylic acids, tricarboxylic acids, and amino acids; and a fluorine-containing anionic surfactant containing not more than 7 carbon atoms.
