<p>PROBLEM TO BE SOLVED: To provide a water- and oil-repellent composition which can impart water and oil repellency to an article even if processed at a low temperature and can apply a water- and oil-repellent treatment providing a soft feeling.SOLUTION: There is provided a water- and oil-repellent composition which essentially contains a copolymer containing a polymerization unit of the following monomer (a) and a polymerization unit of the following monomer (b). Monomer (a): a monomer having a polyfluoroalkyl group in which a fine crystal derived from a polyfluoroalkyl group of a homopolymer of the monomer has no melting point or has a melting point of 50°C or less, Monomer (b): a monomer having an organic group other than the polyfluoroalkyl group in which a fine crystal derived from an organic group of a homopolymer has a melting point of 30°C or more.</p> |
