Abstract
The invention relates to a process for producing a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects with or without a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer has a low conductivity after drying; (b) drying of the first layer; (c) applying an ink comprising a metallo-organic complex in a predetermined pattern on the first layer; (d) decomposing of the ink applied in step (c), thereby forming a pattern having a higher conductivity on the first layer. The invention further relates to a transparent conductive film, comprising areas with lower conductivity and areas with higher conductivity, wherein the areas with higher conductivity and the areas with lower conductivity comprise nanoobjects and in the areas with higher conductivity, the nanoobjects are fused by metal generated by decomposition of a metallo-organic complex.
