<p>Disclosed is an ornament with a thin film formed on the ornament surface. The thin film includes a fluorocarbon-based adsorbed monomolecular film, and the thin film is covalently bonded to the ornament. By contacting the ornament with the non-aqueous solution containing a chlorosilane group at one end and a fluorocarbon chain at the other end, a reaction occurs between hydroxyl groups at the ornament surface and the chlorosilyl groups of the material having a plurality of chlorosilyl grounds. A monomolecular film which is covalently bonded to the ornament surface is thereby obtained. A thin, fluorine-containing, monomolecular film thus can be formed on the ornament such that it is, chemically bonded to the ornament. The film is anti-contaminating, water-and oil-repelling, durable and does not spoil the intrinsic luster of the ornament.</p> |
