A low-reflection transparent conductive multi layer film comprising:
- a transparent substrate;
- a hard coat layer formed on said substrate;
- at least one transparent conductive layer which comprises conductive particles comprising at least one of a metal and a metal oxide, formed on said hard coat layer;
- and a transparent protective layer for the conductive layer, formed on said conductive layer, wherein said protective layer comprises at least one layer having anti-smudge properties and a refractive index different from that of said transparent conductive layer, wherein each layer of said protective layer contains an active energy ray-cured resin having a dielectric power factor of 0.01 or more at 50 Hz and the product of the refractive index and the thickness of the protective layer is from 100 to 200.
A method for electrically grounding a low-reflection transparent conductive multi layer film comprising leading a ground directly from the surface of a protective layer in the conductive multi layer film, wherein the conductive multi layer film comprises:
- a transparent substrate;
- a hard coat layer formed on said substrate;
- at least one transparent conductive layer which comprises conductive particles comprising at least one of a metal and a metal oxide, formed on said hard coat;
- and a transparent protective layer for the conductive layer, formed on said conductive layer, wherein said protective layer comprises at least one layer having anti-smudge properties and a refractive index different from that of said transparent conductive layer, wherein each layer of said protective layer contains an active energy ray-cured resin having a dielectric power factor of 0.01 or more at 50 Hz and the product of the refractive index and the thickness of the protective layer is from 100 to 200.
