Abstract
Methods for producing a transparent conductive film and transparent conductive pattern having superior in-plane uniformity of resistance, by a printing method of slit coating or roll coating of metal nanowire ink. The methods include applying a metal nanowire ink containing metal nanowires, a binder resin containing more than 50 mol % monomer units derived from N-vinylacetamide, and a solvent, to at least one surface of a transparent resin film and drying to form a transparent conductive layer, the application of the metal nanowire ink to the transparent resin film being application by slit coating or roll coating performed using a transparent resin film and metal nanowire ink with which the advancing angle (θa) of the dynamic contact angle of the metal nanowire ink relative to the transparent resin film satisfies 10.0°<θa≤25.0°, and the difference (θa−θr) between the advancing angle (θa) and the receding angle (θr) is 10.0° or higher.
