Abstract: There is provided a silver powder, which is able to obtain a conductive paste having a high thixotropic ratio and a high Casson yield value and which is able to form a conductive pattern having a low resistance, and a method for producing the same. An aliphatic amine such as hexadecylamine is added to a silver powder, the surface of which is coated with a fatty acid such as stearic acid, to be stirred and mixed to form the aliphatic amine on the outermost surface of the silver powder while allowing the fatty acid to react with the aliphatic amine to form an aliphatic amide such as hexadecanamide between the fatty acid and the aliphatic amine.

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.
