WATER- AND OIL-REPELLENT COATING FILM AND ARTICLE CONTAINING SAME
摘要
<p>Provided is a coating film that can more reliably exhibit an excellent water repellency and an excellent oil repellency. This water- and oil-repellent coating film is a coating film formed on a surface of a material in order to impart water repellency and oil repellency, wherein (1) the coating film contains a metal oxide-containing composite particle; (2) the composite particle contains a) a metal oxide particle and b) a covering layer that contains a polyfluoroalkyl methacrylate resin and is formed on the surface of the metal oxide particle; and (3) a value obtained by dividing the fluorine content (weight%) of the composite particle by a surface area (m 2 /g) of the metal oxide particle is 0.025 to 0.180.</p>
