PROBLEM TO BE SOLVED: To provide a transparent conductive film that suppresses coloring of transmitted light and has a high total ray transmittance, and to provide a color tone correction film for a base of the same.SOLUTION: A color tone correction film is formed by laminating a first color tone correction layer, a second color tone correction layer and a third color tone correction layer on one surface of a polyester film base material. A functional layer is, as necessary, laminated on the other surface of the polyester film base material. The first color tone correction layer contains zirconium oxide fine particles and an active energy ray-curable resin, has a refractive index to light at a wavelength of 400 nm of 1.66-1.75, and has a film thickness of 0.4-1.5 μm. The second color tone correction layer contains titanium oxide fine particles and an active energy ray-curable resin, has a refractive index to light at a wavelength of 400 nm of 1.76-1.83, and has a film thickness of 32-70 nm. The third color tone correction layer has a refractive index to light at a wavelength of 400 nm of 1.33-1.53, and has a film thickness of 10-40 nm. A transparent conductive film is formed by laminating a tin-doped indium oxide layer having a refractive index to light at a wavelength of 400 nm of 1.85-2.35, and has a film thickness of 5-50 nm on the third color tone correction layer of the color tone correction film.SELECTED DRAWING: None |
