Abstract
Abstract An ultra-thin, water- and oil-repelling and durable overcoat easily formed on a substrate surface via covalent bonding by applying a finishing agent, in which a chemical adsorbent including at least one chlorosilyl group is mixed in a nonaqueous viscous liquid or a solid medium, to the substrate surface; and an oil-repelling, extremely thin and durable overcoat with a high water-separation property covalently bonded to a substrate surface by applying an organsiloxane-based finishing agent, in which at least one organosiloxane bond chain and chlorosilyl group are mixed in a nonaqueous viscous liquid or a solid medium, to the substrate surface.
