ABSTRACT:
A method for producing an electromagnetic-wave-shielding light-transmitting window member comprising a transparent substrate and a conductive pattern formed by electroless plating on a surface of the transparent substrate. In the method, an ultraviolet-curable resin paste containing an electroless plating catalyst is applied to a surface of a transparent substrate, and the resulting printed pattern is cured by irradiation of ultraviolet light to form a resin pattern. Subsequently, a plating layer is deposited on the resin pattern by electroless plating treatment to form a conductive pattern. The ultraviolet-curable resin paste is selected from a group of sublimable resists and phthalocyanine-based sublimable materials and contains a volatile substance that is volatized by heating or irradiation. By using the ultraviolet-curable resin paste, a good conductive pattern having excellent adhesion to the transparent substrate can be formed with high accuracy, efficiently, and at low cost.
