AQUEOUS WATER- AND OIL-REPELLENT DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide an aqueous water- and oil-repellent dispersion having durable water- and oil-repellency and excellent storage stability.

SOLUTION: The aqueous water- and oil-repellent dispersion contains: (A) a homopolymer or copolymer containing at least one polymerizable compound having a perfluoroalkyl or perfluoroalkenyl group and an acrylate or methacrylate group, or a copolymer containing the polymerizable compound and another compound copolymerizable therewith, (B) an organic solvent which is tripropylene glycol, and (C) a surfactant. The dispersion is effective for reduction of environmental contamination and has durable water- and oil-repellency and excellent storage stability.
