1. An electrical functional layer in which conductive, non-transparent tracks (1) of a thickness in the range of 2 nm to 5 μ
- m are arranged parallel to the surface of a transparent carrier (2), forming a pattern, such that embodied in the pattern is a conductor track spacing which ensures areal conductivity of the electrical functional layer with at the same time transparency for the human eye.

Abstract
Transparent electrically conductive functional layer, production process and use thereof.
The invention concerns a transparent electrically conductive functional layer, in particular a laminate body. The invention makes it possible for the first time to produce thin conductive functional layers for use in resistive touch screens, for example in a printing process. By way of example with a coverage of 5% and adequate conductivity the functional layer still works at 95% transparent for the human eye.
