The present invention provides a process for preparing a light transmissive electromagnetic wave shielding material having an excellent light transmissive property, an excellent electromagnetic wave shielding property, an excellent appearance property and an excellent legibility by a simple method. A process for the preparation of a light transmissive electromagnetic wave shielding material comprising;

Process for preparing light transmissive electromagnetic wave shielding material, light transmissive electromagnetic wave shielding material and display filter

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.

A touch panel having excellent durability, in which depression is scarcely generated on the surface of the touch panel by pushing the surface with a pen, and a transparent conductive film and plate useful in the touch panel are provided. The transparent conductive film comprises a first polymer film having a transparent conductive thin layer thereon and a second polymer film having a hardcoat layer thereon, the first and second polymer films being bonded each other through an adhesive layer such that a surface having no transparent conductive thin layer of the first polymer film faces a surface having no hardcoat layer of the second polymer film, wherein work of the adhesive layer in elastic deformation is not less than 60%. The transparent conductive plate is provided with the adhesive layer, the touch panel is provided with the transparent conductive film or plate as an upper or lower electrode.

An adhesive composition for use in joining a polarizer plate to a substrate of a liquid crystal cell contains as a main component (1) an ethylene-vinyl acetate copolymer, (2) a copolymer of ethylene, vinyl acetate, and an acrylate and/or methacrylate monomer, (3) a copolymer of ethylene, vinyl acetate, and maleic acid and/or maleic anhydride, (4) a copolymer of ethylene, an acrylate and/or methacrylate monomer, and maleic acid and/or maleic anhydride or (5) an ionomer resin in the form of an ethylene-methacrylic acid copolymer having a metal ion for binding molecules thereof. The composition is thermosetting when it contains an organic peroxide. The composition is photo-curable when it contains a photosensitizer.
