Abstract:
A transparent conductive laminate for obtaining a transparent touch panel improved in the durability in writing which has been required of conventional transparent touch panels and in durability in writing in marginal regions of the transparent touch panel (margin pushing durability). Also provided is a transparent touch panel employing the laminate. The transparent conductive laminate comprises a polymer film and, superposed on at least one side thereof in the following order, a cured resin layer, a transparent conductive layer (1), and another transparent conductive layer (2). The transparent conductive layer (1) is a crystalline transparent conductive layer containing no organic ingredient. The transparent conductive layer (2) comprises: an ionizing-radiation-cured resin, thermoplastic resin, polymer of a metal alkoxide other than alkoxysilanes, or thermally cured/crosslinked resin; and at least one kind of fine particles (A) of a conductive metal oxide or metal which have an average primary-particle diameter of 100 nm or smaller.
