FIELD: personal and household items.
SUBSTANCE: invention provides a water- and oil-repellent coating film. Water- and oil-repellent coating film is described which is a coating film obtained on the surface of a material to endow it with water- and oil-repellency, wherein (1) the coating film comprises silica-containing composite particles; (2) the composite particle comprises (a) a silica particle and (b) a coating layer, which contains a polyfluoroalkyl methacrylate polymer, and is applied to the surface of the silica particle; and (3) the value, obtained by dividing the fluorine content (wt %) of the composite particle by the specific surface area (m2/g) of silica particles, is from 0.025 to 0.180. Also described is a packaging material containing a water- and oil-repellent coating film.
EFFECT: technical result is obtaining a coating film with high water- and oil-repellent properties.
