By reducing the exchange, it is possible to prevent excessive rise and fall of room temperature. Therefore, the near-infrared absorbing material can be used as a representative energy-saving material, has been actively applied in the building and automotive industry.
- Near-infrared absorbing materials used in films attached to windows of automobiles and buildings should have good near-infrared absorption performance and minimize absorption in the visible region.
- the driver's vision may be blurred or the view of the house may be deteriorated, and additional energy may be required for internal lighting. This is because the color may not be natural.

Difficult to manage, and weather resistance problem occurs in the product, it is difficult to actually use.
- anionic materials such as the antimony fluoride ions, which are widely used in recent years, may be used as a near-infrared absorbing material with appropriate physical properties, but toxic substances such as hydrofluoric acid may be emitted due to fluorine atoms present in the material. It is not suitable for use in places close to the human living environment such as cars and automobiles, and the durability of the product (film, etc.) may be degraded by the hydrofluoric acid.
