LIGHT-TRANSMITTING CONDUCTIVE MEMBER AND PATTERNING METHOD THEREOF

摘要

To provide a light transmitting electrically conductive member in which an electrically conductive layer containing silver nanowires can be patterned into an electrically conductive region and a non-electrically conductive region and in which optical characteristics of the non-electrically conductive region can be improved, and also to provide a method for patterning the light transmitting electrically conductive member.
[Solution] A light transmitting laminate material in which an electrically conductive layer 12 including an overcoat layer 14 and silver nanowires 13a embedded therein is formed on a surface of a light transmitting base film 11 is used, and a step of treating a surface of the electrically conductive layer 12 which is not covered with a resist layer 41 using an iodine solution to at least partially iodize the silver nanowires 13a and a step of applying a thiosulfate solution to the surface of the electrically conductive layer 12 which is not covered with the resist layer 41 to remove a silver iodide exposed to a surface of the overcoat layer 14 are performed. Since a white cloudy or a whitened silver iodide is removed, the optical transmission characteristics of the non-electrically conductive region can be improved.
