Abstract:
An aqueous-dispersing composition comprising an aqueous dispersion of fluorine-containing polymer particles, a colloidal silica and an organoalkoxysilane, and containing said colloidal silica, in solid content, in an amount of more than 50 parts by weight up to 300 parts by weight and said organoalkoxysilane in an amount of 0.1 to 20 parts by weight on the basis of 100 parts by weight in solid content of an aqueous dispersion of fluorine-containing polymer particles, and said fluorine-containing polymer particles are fluorine-containing seed polymer particles which contain a fluoroolefin unit in an amount of 20 to 90% by mole on the basis of the whole seed polymer, and are obtained by seed-polymerizing a monomer having a reactive &agr;,&bgr;-unsaturated group in the presence of fluorine-containing polymer particles.
