Abstract
A transparent electrically conductive film and processes for the production thereof are described, said film comprising a metallic oxide wherein the metallic component comprises from 60 to 95 wt % indium and from 40 to 5 wt % tin formed on the surface of a plastic base, wherein the weight ratio of the tin to the indium changes continuously from the outer surface to the inner surface in such a manner that the ratio on the inner surface of the film is appreciably lower than the average ratio of the film and the ratio on the outer surface of the film is appreciably higher than the average ratio of the film.
