Title: LAMINATE FOR TOUCH PANELS, AND TOUCH PANEL
Abstract:
The present invention provides: a laminate for touch panels, which provides a touch panel that is not susceptible to malfunctioning if used in the touch panel in combination with a display device, and which is capable of suppressing ion migration between metal thin wires; and a touch panel which comprises this laminate for touch panels. A laminate for touch panels according to the present invention is a laminate for touch panels, which is arranged on the viewing side of a display device. This laminate for touch panels is sequentially provided with a first transparent protective substrate, a first adhesive layer, a conductive film having at least metal thin wires, a second adhesive layer and a second transparent protective substrate in this order. When this laminate for touch panels is arranged on a display device, the second transparent protective substrate is positioned on the display device side, and the second transparent protective substrate is a barrier laminate having at least one organic layer and at least one inorganic layer. The second transparent protective substrate has a water vapor transmission rate of 0.001 g/m2/24h or less (at 40°C at 90% RH), and the amount of metal contained in the metal thin wires per unit area is 0.010-10 g/m2.
