Abstract
A method for patterning a light transmitting electrically conductive member uses a light transmitting laminate material in which an electrically conductive layer including an overcoat layer and silver nanowires embedded therein is formed on a surface of a light transmitting base film and includes a step of treating a surface of the electrically conductive layer which is not covered with a resist layer using an iodine solution to at least partially iodize the silver nanowires and a step of applying a thiosulfate solution to the surface of the electrically conductive layer which is not covered with the resist layer to remove a silver iodide exposed to a surface of the overcoat layer. Since a white cloudy or a whitened silver iodide is removed, the optical transmission characteristics of the non-electrically conductive region can be improved.
