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.

Abstract: The invention relates to a patterned transparent conductive film, comprising areas with higher conductivity and areas with lower conductivity, wherein in the areas with higher conductivity nanoobjects are disposed in a binder matrix such that the nanoobjects are interconnected and thereby form an area with higher conductivity and wherein in the areas with lower conductivity the nanoobjects are structurally intact and are coated with an insulating coating material. The invention further relates to a process for producing such 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 and a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer is conductive after drying; (b) drying of the first layer; (c) applying a mixture comprising an insulating coating material or a precursor of an insulating coating material on that parts of the first layer which shall form the areas with lower conductivity, wherein the insulating coating material or the precursors form an insulating coating around the electrically conductive nanowires; (d) drying of the coated substrate.
