Abstract:
1. An aqueous water- and oil-repellent dispersion composition comprising a polymer obtained by polymerizing an emulsion of a polymerizable compound wherein the polymerizable compound is emulsified into water so that an average particle diameter is at most 100 nm and an integrating sphere turbidity is at most 20 (kaolin), at least one polymerization dispersant selected from the group consisting of (i) surfactants having at least 8 mol of added ethylene oxide per one mol of hydrophobic group, and (ii) protective colloids is added to the emulsion of the polymerizable compound before the polymerization, the emulsion of the polymerizable compound is free of an organic solvent, and the polymerizable compound comprises a polymerizable monomer having a perfluoroalkyl or perfluoroalkenyl group and an acrylate or methacrylate group.
