Substrate and negative imaging method for providing transparent conducting patterns

Provided are processes for making a transparent conducting pattern. The invention is also directed to electronic devices containing such transparent conducting patterns. Further provided is a substrate comprising a base film and a transparent conducting layer disposed on the base film; wherein the substrate has an OD of about 0.1 to 0.6 at 830 nm, and the transparent conducting layer comprises polyethylene dioxythiophene and has an OD of less than 0.1 in the range of 400 to 700 nm.
