Abstract
The present invention provides a method for preparing a conductive pattern, comprising a pattern forming step of forming a conductive pattern on a substrate; and a blackening processing step of blackening the surface of the conductive pattern by immersing the conductive pattern in an aqueous solution containing reducing metal ions to oxidize the surface of the conductive pattern, and a conductive pattern prepared therefrom.
