ABSTRACT:
According to the invention, a fluorine-based or siloxane-based chemical adsorbed film containing a fluorocarbon compound can be formed on a given substrate surface in a laminated state and through chemical bonds (i.e., covalent bonds) with the substrate, it is possible to obtain a laminated film which has satisfactory adhesion to the substrate, is substantially pin-hole free and is very thin. Further, since the outermost layer may be substituted by fluorocarbon groups or hydroxyl groups, it is possible to obtain a film which has excellent water- and oil-repelling properties or hydrophilic and oil-repelling properties and can replace fluorine-based coating films, thus improving the performance of products requiring a coating having a water- and oil-repelling resistant property, weather-resistant property, wear-resistant property and so forth which are desirable in electric products, vehicles, industrial devices and so forth.
