ABSTRACT:
An ultra thin, water and oil repelling and durable overcoat is easily formed on a substrate surface via covalent bonding by applying a finishing agent of the invention, comprising a chemically adsorptive compound with a chlorosilyl group and a nonaqueous viscous liquid or solid medium, on the substrate surface. A finishing agent, comprising a chemically adsorptive compound with a chlorosilyl group and a nonaqueous viscous liquid or solid medium, is applied on a substrate surface comprising hydrophilic groups. The substrate surface is then reacted with the chemically adsorptive compound at room temperature, and the agent containing unreacted chemically adsorptive compound is removed. The generation of hydrochloric acid gas can be prevented by adding tertiary amine or amide in the molar amount of one to three times more than the chemically adsorptive compound contained in the finishing agent.
