Embodiment 1）

[0093] (Example 1) Example of using plate glass:

[0094] 50.0 g of an aqueous dispersion of a composite of poly(3,4-ethylenedioxythiophene) and polystyrenesulfonic acid (manufactured by Heraeus Co., Ltd.: CleviosP, conductivity 0.09 S / cm, solid content 1.3%), 0.5 g of surfactant (solids 10%), 0.05 g of leveling agent (solids 100%), 2 g of water, and 8 g of ethanol were mixed and stirred for 30 minutes. The resulting mixture was filtered through a 400-mesh SUS-made sieve to prepare a coating agent.

[0095] The obtained coating agent was coated on a blue plate glass (manufactured by advanced materials technology Co., Ltd.: AMT-8292) with a thickness of 0.7 mm by the bar coating method using a wire bar No. 8 (wet film thickness 18 μm), and Dry at 100° C. for 1 minute to obtain a base.

Embodiment 2）

[0096] (Example 2) Example of using plate glass:

[0097] Instead of CleviosP in Example 1, Clevios P ​​HC V4 (manufactured by Heraeus Co., Ltd.: conductivity 0.23 S / cm, solid content 1.2%), the matrix was obtained by the same method as in Example 1.

Embodiment 3）

[0098] (Example 3) Example of using plate glass:

[0099] Instead of CleviosP in Example 1, Clevios PH1000 (manufactured by Heraeus Co., Ltd.: conductivity 0.46 S / cm, solid content 1.1%), the matrix was obtained by the same method as in Example 1.

Abstract

Provided is an infrared-reflecting substrate that can be readily produced by coating the surface of a base material, and that exhibits superior infrared-reflecting performance while also exhibiting high light-transmitting performance at a low film thickness. This infrared-reflecting substrate includes an infrared-reflecting layer formed by coating a transparent base material with a coating agent containing a complex of poly(3,4-disubstituted thiophene) and a polyanion, and exhibits a total light transmittance of 60% or greater. Preferably, the complex exhibits an electroconductivity of 0.15 (S / cm) or greater. Preferably, the infrared-reflecting layer has a film thickness of 0.50 [mu]m or less.

Description

technical field [0001] The present invention relates to a coating agent for forming a transparent film exhibiting infrared reflection performance, an infrared reflection film formed using the coating agent, and an infrared reflection substrate including the film. Background technique [0002] Infrared rays refer to electromagnetic waves with longer wavelengths than red light and shorter wavelengths than millimeter-wavelength radio waves, and their wavelengths are roughly distributed in the range of 0.7 μm to 1 mm. According to the length of the wavelength, it is divided into near-infrared, mid-infrared, and far-infrared. It is widely known that mid-infrared rays, far-infrared rays, etc. having long wavelengths are absorbed by an object, and that the temperature of the object rises due to this. [0003] Conventionally, research has been conducted on suppressing the temperature rise of the object by providing a thin film reflecting infrared rays on the surface of the object b...
