Abstract
A fluororesin aqueous dispersion comprising from 20 to 70 mass % of microparticles of a fluororesin and from 1 to 12 mass %, based on the mass of the fluororesin, of a non-ionic surfactant represented by the formula (1):R1—O-A-X (1)wherein R1 is a C6-18 alkyl group, O is an oxygen atom, A is a polyoxyalkylene group comprising from 1 to 3 oxybutylene groups and from 5 to 20 oxyethylene groups, and X is a hydrogen atom or a methyl group.
