Abstract
Provided is a light-transmitting conducive laminate which is moldable and has good designability. A light-transmitting conductive laminate is provided in which at least a surface skin material and a transparent conductive base are sequentially laminated from the input side.
Claims11
A light-transmitting conductive laminate at least comprising a surface material and a transparent electrically conductive substrate laminated in this order from an outer side of the light-transmitting conductive laminate,
- wherein the surface material comprises a layer consisting of at least one member selected from the group consisting of woven fabric, knitted fabric, nonwoven fabric, synthetic leather, and artificial leather and a surface of the surface material has been napped,
- wherein the light-transmitting conductive laminate has a total light transmission of at least 20%,
- wherein the light-transmitting conductive laminate has a visual recognizability of see-through letters and symbols of the surface material, as determined by a light arranged on a back surface of the transparent conductive substrate to display a design on a surface of the surface material by illuminating the light,
- wherein the surface material has an anti-see-through property of at least 90%, where anti-see-through property (%)=(lightness of the light-transmitting conductive laminate in the use of a black tile)/(lightness of the light-transmitting conductive laminate in the use of a white tile)×100, and
- wherein a display mark is printed on the transparent conductive substrate.
