Abstract
The present invention provides an organosol composition that is stable even in the case that the PTFE particle content is high. The present invention relates to an organosol composition of PTFE particles, comprising PTFE 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 PTFE particles (A) is not lower than 50% by mass of the total amount of the PTFE particles (A) and the polymer (B), and (3) the precipitation ratio of the PTFE particles after 48 hours is not higher than 60% when the total solids concentration of the PTFE particles (A) and the polymer (B) is 5% by mass.
