Abstract:
1. A transparent electroconductive laminate comprising an organic polymer film having stacked thereon a transparent electroconductive layer, wherein: an optical interference layer and a transparent electroconductive layer are sequentially stacked on at least one surface of the organic polymer film, the optical interference layer comprises a high refractive-index layer and a low refractive-index layer, with the low refractive-index layer being in contact with the transparent electroconductive layer, the high refractive-index layer and the low refractive-index layer each is composed of a crosslinked polymer, at least either one of the high refractive-index layer and the low refractive-index layer containing metal oxide and/or metal fluoride ultrafine particles having a primary diameter of 100 nm or less, the low refractive-index layer has a refractive index of 1.6 or less, the high refractive-index layer has a larger refractive index than the low refractive-index layer, and the crosslinked polymer of at least one of the high refractive-index layer and the low refractive-index layer is one formed by hydrolysis and condensation polymerization of a metal alkoxide.
