(57) [Abstract] [Object] To provide a light-transmitting electromagnetic wave shielding material having excellent visibility and a high electromagnetic wave shielding effect, and a method for producing the same. [Constitution] A 100 μm-thick polyester film is used as a transparent substrate 1, and a 35 μm-thick copper foil is formed on a metal layer 2 And line width of 10μ by photolithography The metal layer 2 was patterned in a grid pattern having a size of 100 × 100 μm and a size of 100 μm. A conductive wire is connected to this, and carbon black 1 %, An aminated epoxidized polybutadiene (number-average molecular weight: about 1000), 20%, and 1% triethylamine in an aqueous solution containing 10% voltage for 1 minute to form a black electrodeposited layer 3 having a thickness of 1 μm. The substrate was dried at 60 ° C. for 30 minutes, and after cooling, a film was laminated thereon to obtain a translucent electromagnetic wave shielding material. |
