Title: TRANSPARENT ELECTROCONDUCTIVE LAMINATE, METHOD FOR MANUFACTURING SAME, ELECTRONIC PAPER USING SAME, AND TOUCH PANEL USING SAME
Abstract:
A transparent electroconductive laminate having, on a transparent substrate, an undercoat layer containing an inorganic oxide and an electroconductive layer containing carbon nanotubes in the stated order, wherein the transparent electroconductive laminate is characterized in that: conditions [A] and/or [B] is satisfied; and the proportion of the surface resistance value after being subjected to a 1-hour wet heat treatment at 60ºC and a relative humidity of 90% and then being left standing for 3 minutes at 25ºC and a relative humidity of 50%, relative to the surface resistance value before the treatment, is 0.7 to 1.3. A method for manufacturing same, electronic paper using same, and a touch panel using same. [A] The white reflectance is from greater than 70% and to no greater than 85%, and the surface resistance value is 1.0 × 102 Ω/□ to 1.0 × 104 Ω/□. [B] The total light transmittance is greater than 88% and no greater than 93%, and the surface resistance value is 1.0 × 102 Ω/□ to 1.0 × 104 Ω/□. Provided is a transparent electroconductive laminate having excellent heat resistance stability, wet heat resistance stability, and transparent electroconductivity.
