On the other hand, a spray method in which a liquid raw material is sprayed is known as a thin film method that provides a low-cost and highly durable coating. There are many types of coatings obtained by spraying, but those with low transmittance to near-infrared light are mainly made of tin oxide and antimony oxide, as shown in U.S. Pat. No. 2,564,708. An example of this is a composite oxide thin film.

When O31 is 2.5 to 40%, the visible light transmittance (TL
)5 to 35%, solar transmittance of 15 to 45%, which satisfies the purpose of cutting near-infrared light, and has a visible light diffuse transmittance of less than 2%, which is perfect for practical use. It was found that near-infrared light-cutting glass could be obtained. Furthermore, the range was further narrowed and the composition of the film was changed to SnO265.
~85% Sb2Oa 15-35%, the visible light transmittance is 5-20% and the solar transmittance is 15-30%, and in this case, it is possible to obtain an even more excellent film with a diffuse transmittance of 1.7% or less. can.

よって基本的には影響されない。Note that the diffused transmittance, which is a problem in the present invention, has a deep relationship with the crystallinity of the oxide thin film. Generally, the temperature and film thickness during film deposition tend to show a correlation with the crystallinity of the film, but the diffusion transmittance of tin oxide and antimony oxide raw materials and the type of solvent revealed in this invention The effectiveness of is essentially unaffected by these factors.

ととした。Furthermore, when expressing the degree of cloudiness of a film, it is generally expressed by a haze rate, but in the case of a colored film, the haze rate becomes a high value because the total transmittance is low. Therefore, here, the haze value is expressed by the diffuse transmittance (Td) obtained by multiplying the haze rate by the total transmittance.
