Patent ID: 7858145

Claim:
A method for producing an electroconductive member pattern, comprising the steps of: forming a resin film on a surface of a substrate; incorporating a first metal component into the resin film by applying a liquid, which contains a complex containing the first metal component, and a second metal component different from the first metal component, to the resin film; adding, to the liquid, a compound which reacts with the second metal component to form a non-polar complex, or a compound which reacts with the second metal component to form in the liquid a complex opposite in polarity to an ion of the second metal component, before or during the step of incorporating the first metal component into the resin film; and forming an electroconductive member pattern by baking the resin film incorporating the first metal component, wherein the second metal component comprises at least one of Ca, Mg, Ba, and Sr, and wherein the compound comprises at least one selected from iminodiacetic acid, nitrilotriacetic acid, ethylenediamine tetraacetic acid, diethylenetriamine pentaacetic acid, hydroxyethylethylenediamine triacetic acid, and methylglycine diacetic acid, wherein the liquid is an aqueous solution, the complex containing the first metal component is tris(2,2′-bipyridine) ruthenium acetate, the compound is nitrilotriacetic acid, and the non-polar complex formed with the second metal component suppresses incorporation of the second metal component into the resin film.
