TRANSPARENT CONDUCTIVE LAMINATE AND TRANSPARENT TOUCH PANEL
摘要:
The present invention provides a transparent electroconductive laminate suitable for use in combination with a display device such as a liquid crystal display, and a transparent touch panel having the transparent electroconductive laminate. The transparent electroconductive laminate comprises a transparent organic polymer substrate 33 having, on at least one surface thereof, a hardcoat (HC) layer 33h, an optical interference layer 32, and a transparent electroconductive layer 31 in this order. The transparent electroconductive laminate satisfies the following conditions: the refractive indexes n 3 and n 3h of the transparent organic polymer substrate and the HC layer satisfy the following formula: |n 3 -n 3h |‰¤0.02, the thickness of the HC layer is from 1 to 10 µm, the thickness of the optical interference layer is from 5 to 500 nm, the thickness of the transparent electroconductive layer is from 5 to 200 nm, the total light transmittance is 85% or more, and the b* value is from -1.0 to less than 1.5 and the transparent touch panel has the transparent electroconductive laminate.
