Examples of the alcohol having 3 or less carbon atoms include methyl alcohol, ethyl alcohol, propyl alcohol, and isopropyl alcohol. The content of the alcohol having 3 or less carbon atoms in the coating solution is preferably 10% by weight or more,
If the content is less than 10% by weight, the drying speed after application to the substrate is insufficient, and the film forming property is undesirably reduced.

It is extremely important that the coating liquid for forming a low refractive index transparent thin film layer contains 20 to 50% by weight of water, and the water content is less than 20% by weight or 50% by weight.
If the amount exceeds 30% by weight, the original purpose cannot be achieved. Although the reason is not clear, it is considered as follows. That is, when the content of water is less than 20% by weight, the viscosity of the obtained coating liquid for forming a transparent thin film layer is high, the transparent thin film layer becomes uneven, the amount of light scattering increases, and the haze value increases. On the other hand, if the water content is more than 50% by weight, the drying speed of the coating film after spraying is too low, bleeding occurs, the film surface is glaring, and the interference color becomes rainbow.

The coating liquid for forming the low-refractive-index transparent thin film layer contains a silicone-based surfactant as a leveling agent in an amount of 0.001.
Preferably, it contains 0.1 to 0.1% by weight. This silicon-based surfactant is used to lower the surface tension of the coating liquid for forming a low-refractive-index transparent thin film layer to improve coating properties. If the addition amount of the silicon-based surfactant is less than 0.001% by weight, the action as a leveling agent is insufficient.
If the addition amount exceeds 0.1% by weight, the film strength decreases and the haze value increases, which is not preferable.

Further, the coating liquid for forming a low refractive index transparent thin film layer preferably contains colloidal silica in an amount of 0.05 to 0.1% by weight. The colloidal silica adjusts the refractive index,
This is for lowering the haze value.

Further, the coating liquid for forming the low-refractive-index transparent thin-film layer includes diacetone alcohol, cellosolve, glycol,
It is preferable to include at least one selected from the group consisting of octanol and N-methyl-2-pyrrolidone. When these additives are added in an amount of about 0.001 to 30% by weight, they have a function of adjusting the drying time of the coating film, and the film forming property is improved. In addition, a solvent having a higher boiling point than water remains in the coating film to the end at the time of drying, and has an effect of making the film thickness uniform and preventing aggregation of solids. Further, an organic or inorganic dye or pigment may be added to the coating liquid for forming a low refractive index transparent thin film layer.

As described above, the coating liquid for forming a low refractive index transparent thin film layer according to claim 1 of the present invention comprises, in the coating liquid, silicon alkoxide and / or a hydrolysis product thereof;
Since it contains at least an alcohol having 3 or less carbon atoms and 20 to 50% by weight of water, even if a spray coating method is used instead of the conventional spin coating method, an antireflective transparent conductive film formed by the spin coating method is used. In addition to being able to form an anti-reflective transparent conductive film with almost the same optical properties as the film and having a uniform thickness in a relatively short time, the required amount of coating liquid is small and the coating surface can be reduced by dust. Is hard to get dirty,
This has the effect of improving the production yield and eliminating the need for preparing a highly clean coating environment such as a clean room.

Further, in the antireflection transparent conductive film according to claim 5, a low refractive index transparent thin film layer formed by using the coating liquid for forming a low refractive index transparent thin film layer is laminated on the transparent conductive layer. Since the low refractive index transparent thin film layer formed on the upper layer is not uneven, and the haze value does not increase due to an increase in the amount of light scattering, and Since the film surface does not glare due to bleeding and the interference color becomes light purple to blue purple, the optical characteristics such as antireflection property and visibility are low-refractive-index transparent thin films manufactured by spin coating. This has the effect of having optical characteristics substantially equivalent to those of the antireflective transparent conductive film having the layer.
