(57) [Summary] [Structure] Tin-doped indium oxide (ITO) powder; lower alkoxide of Si, Ti, Zr or Al as a binder (Eg, ethyl silicate); Phosphate group as a binding aid, A titanate-based or aluminum-based coupling agent containing a phosphorous acid group or an ester group thereof (for example, bis (Dioctyl pyrophosphate) oxyacetate titanate); and a solvent (eg, alcohol and / or water) for forming a transparent conductive film. [Effect] When this composition is applied to a transparent substrate and dried at less than 200 ° C, the transparency is high and the surface resistance is 1 × 10 5 Ω. A transparent conductive film having an electric conductivity of / □ or less is obtained. Further firing at 200-400 ℃ gives a surface resistance of 1 × 10 4 Ω. / □ or less. Useful for antistatic film, electrode / circuit formation. |
