Estimating the term…
A fluororesin-metal oxide mixed dispersion (sol) with excellent operability and workability provided in a coating step is obtained by mixing aqueous dispersion of fluororesin particle, and particle sol of metal oxide with suitable pH value that is any one of titanium oxide, zirconium oxide, lanthanum oxide, neodymium oxide, cerium oxide, or tin oxide. Both the fluororesin particle and the metal oxide particle float and disperse without coagulation precipitation, gelation and solidification, and/or phase separation. The floating and dispersion state is stably maintained under room temperature storage for three days or more. Water contact angle of a solid product obtained by evaporation and scattering of a solvent from the fluororesin-metal oxide mixed dispersion is 130 degrees or less, and surface resistivity is 2.0×1012Ω/□ (ohm/square) or less.
