Electroconductive film laminate comprising transparent pressure-sensitive adhesive layer

A double-sided transparent electroconductive film laminate comprising:

• a transparent film substrate;
• a first transparent electroconductive layer on one of opposite surfaces of the transparent film substrate;
• a second transparent electroconductive layer on the other surface of the transparent film substrate;
• a transparent, first pressure-sensitive adhesive layer on a surface of the first transparent electroconductive layer on a side opposite to the transparent film substrate;
• and
• a transparent, second pressure-sensitive adhesive layer on a surface of the second transparent electroconductive layer on a side opposite to the transparent film substrate,
• wherein each of the first and second pressure-sensitive adhesive layers comprises:
• a base adhesive zone made essentially of a transparent base pressure-sensitive adhesive material and formed over a given range from one principal surface of the pressure-sensitive adhesive layer in a thickness direction of the pressure-sensitive adhesive layer;
• and
• a transparent, adherent, refractive index adjustment zone formed over a given range from the other principal surface of the pressure-sensitive adhesive layer in the thickness direction, the refractive index adjustment zone being in contact with a corresponding one of the first and second transparent electroconductive layers, and having a refractive index greater than a refractive index of the base pressure-sensitive adhesive material.
