本発明は、十分な可視光線透過率を有する赤外反射物品
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an infrared reflective article having sufficient visible light transmittance.
［従来の技術］

ソーラーコントロールとしての働きも合わせ持つことに
なり、より好ましい。[Prior Art] Conventionally known infrared reflective articles include:
There is a type called solar control, which is mainly used to reduce the cooling load, and a type called heat mirror, which is used mainly to reduce the heating load. The minimum characteristics required for the latter are high transmittance in the visible range and sufficiently high reflectance in the infrared range, but if the reflectance in the near-infrared range can be increased, it will also work as a solar control device. It is more preferable to have both.
従来このタイプの熱線反射ガラスとしては（１）金属の

示されている。Conventionally, this type of heat-reflecting glass has (1) a thin metal film (2) a doped oxide semiconductor film (3) a three-layer structure of dielectric film/metal film/dielectric film. type was known. Specifically (as Au, Ag
, Cu g film, etc. are used, and (2) is '3n02. A film of 5000 Å or more such as In2O3 is used. As for (3), a structure in which an Ag film is sandwiched between dielectric films is disclosed in Japanese Patent Publication No. 47-8315.
これらのうち（１）のタイプでは赤外域での反射率を十

る。又、（２）のタイプでは赤外域での反射率を十分高
くするためには膜厚が５ｏｏｏÅ以上と大きくなる点と
、近赤外域での反射率を上げられないなどの欠点がある
。Among these types, type (1) requires the thickness of the metal film to be increased in order to sufficiently increase the reflectance in the infrared region, and the drawback is that the transmittance in the visible region decreases. Further, type (2) has drawbacks such as the fact that the film thickness must be as large as 500 Å or more in order to sufficiently increase the reflectance in the infrared region, and the reflectance in the near-infrared region cannot be increased.
これに対しく３）のタイプでは金属膜を挟んだ誘電体膜
が反射防止膜として作用するため、赤外域での十分高い
反射率と可視域での高い透過率とを、全体として１００
０Å以下の膜厚で実現できるなどの利点があり、広く用
いられている。On the other hand, in type 3), the dielectric film sandwiching the metal film acts as an antireflection film, so it has a sufficiently high reflectance in the infrared region and a high transmittance in the visible region.
It has the advantage that it can be realized with a film thickness of 0 Å or less, and is widely used.
しかしこのタイプのものでも、可視域での高透過率を得

好ましくは１５０Å以下であることが必要であるため、

ンが限られてしまい、意匠性の点からは大きな欠点とな
っていた。However, even with this type, in order to obtain high transmittance in the visible range, the thickness of the intermediate metal film must be approximately 200 Å or less.
Since it is necessary that the thickness is preferably 150 Å or less,
The reflectance in the infrared region is about 95% at most, and therefore the emissivity is about 5%. In addition, the reflection in the near-infrared region does not increase, and the solar energy reflectance is about 25% or less.Furthermore, as will be described later as a comparative example, the 1-spectral reflection characteristics are U-shaped in the visible region, and the reflected color is Since it can only produce purple-based tones, variations in one color are limited, which is a major drawback from a design point of view.
以上をまとめると、従来の技術では

十分であり、更に
（２） 反射色調が紫系統に限られる（３） 近赤
外域での反射の立上がりが鈍いという欠点を有していた
のである。To summarize the above, in the conventional technology, (1) type (3) is the best in order to obtain high transmittance in the visible range and sufficiently high reflectance in the infrared range, but it is still insufficient, and furthermore, ( 2) The reflected color tone is limited to purple. (3) The reflection has a slow rise in the near-infrared region.

The optimal number is 200 people, 80 to 250 people for the fourth layer Ag film, and 200^600 people for the fifth layer ZnO film. These film thickness ranges have been established in order to achieve high transmittance in the visible range, and if the film thickness deviates from this range, the interference condition will be violated and the antireflection effect will not be achieved. visible light transmittance decreases.

が最も好ましい。It is preferable for the silver film to be thicker in order to sharpen the rise in reflectance in the near-infrared region, but as the transmittance decreases, the low reflection region becomes narrower, resulting in variations in reflective color tone. It is accompanied by side effects. On the other hand, from the viewpoint of increasing transmittance and freedom of color tone, the thickness of the silver film is
Although r is preferable, the rise of the reflectance in the near-infrared region becomes slow, and the reflectance in the infrared region also decreases. Therefore, it is most preferable that the thickness of the silver film is in the range of 80 to 110.

A boundary layer may also be inserted.
