METHOD FOR MANUFACTURING TRANSPARENT CONDUCTIVE FILM

WIPO Patent Application WO/2021/131099

A1

[Problem] To provide a transparent conductive film including metal nanowires that has good optical characteristics and electrical characteristics and substantially no in-plane resistance anisotropy. [Solution] A method for producing a transparent conductive film including a conductive layer including a metal nanowire and a binder resin, the method comprising a preparation step of preparing a coating liquid including the metal nanowire and the binder resin, and a coating step of coating the coating liquid on one main surface of a transparent base material. The method is characterized in that the coating step is performed with a bar coater using a bar having a friction coefficient of the material constituting the bar surface of 0.05-0.45, a relative movement speed (coating speed) V (mm/sec) of the transparent base material with respect to the bar when coating the coating liquid on the one main surface of the transparent base material is 2000 ≥ V ≥ 350, a ratio P/H of the pitch (P) to the depth (H) of a groove formed on the bar is 9-30, and the inclination angle between the longitudinal direction of the bar and the groove forming direction is in the range of 60-88˚.
