Abstract
A composition for primer layer coating of a water- and oil-repellent coating layer so as to enhance the durability of the water- and oil-repellent coating layer, comprises a mixture which comprises at least one of a silicon oxide (SiOx) and titanium (Ti) compound, an aluminum (Al) compound and a zirconium (Zr) compound. A preparation method may comprise: preparing a glass or polymer substrate; forming, on the substrate, a portion on which a fingerprint-resistant layer is to be deposited within the substrate by etching; depositing a primer layer consisting of the composition on the surface of the substrate including the portion where the water- and oil-repellent coating layer is deposited; forming the water- and oil-repellent coating layer on the deposited primer layer; and purging the substrate on which the water- and oil-repellent coating layer is formed. The method has excellent wear-resistance, salt water resistance, chemical resistance and cosmetics resistance.
