Abstract:
1. An organosol composition of polytetrafluoroethylene particles, comprising polytetrafluoroethylene particles (A), a polymer (B), and an organic solvent (S), wherein (1) the polymer (B) is soluble in the organic solvent (S), (2) the amount of the polytetrafluoroethylene particles (A) is not lower than 50% by mass of the total amount of the polytetrafluoroethylene particles (A) and the polymer (B), (3) the precipitation ratio of the polytetrafluoroethylene particles after 48 hours is not higher than 60% when the total solids concentration of the polytetrafluoroethylene particles (A) and the polymer (B) is 5% by mass based on the total mass of the organosol composition, and (4) the amount of the polytetrafluoroethylene particles (A) based on a solids content of the organosol composition is not lower than 30% by mass.
