Description

[Detailed description of the invention]

a) Industrial Field of Application The present invention relates to a light-transmitting sheet that transmits visible light but absorbs or reflects external light. More specifically, it relates to a selectively transparent sheet that transmits visible light and absorbs or reflects near-infrared light to infrared light. In general, thin sheets of conductive metals such as gold, copper, copper, and various alloys mainly composed of these are used.・It is known that by controlling the thickness of the helment thin film, it is possible to obtain a film that selectively reflects light in a specific wavelength range.In particular, it is transparent in the clear vision area and selectively reflects infrared wavelengths. The laminate is effective as a heat ray reflective film and in terms of saving energy in houses, etc., and utilizing solar energy. In order to further improve energy saving efficiency, it is better to have more selectivity in the transmission characteristics of the visible light region (450 nm to 700 nm) and the near infrared region (701 nm to 2100 nm) in the energy key distribution of the Taiyang rays. Effective.In other words, in the solar energy distribution, it is not felt by the human eye, but it further reduces the transmission characteristics of the near-infrared region, where about 50 times the solar reflected heat rays exist, and further improves the transmission characteristics of the visible light region. It is more effective for heat insulation and does not impair transparency, so it can be applied to various fields without affecting the surrounding environment or safety. Examples of application fields include: Improving the heat insulation of monitoring windows, etc. during high-temperature work, and further improving the cooling effect by improving the blocking properties of large diameter energy that enters through the windows of buildings, cars, trains, and other vehicles. Heat-insulating housing improvements and refrigeration of transparent food containers, Examples include further improvement of the cold storage effect in a refrigerated circular case. b) Prior art These optical interference filters having selective permeability are generally known as the Fugufuri Pair filter (Fabry-P).
erot filter) is well known. This is known as an interference filter that sandwiches a transparent dielectric material with a specific optical thickness between opposing semi-transparent mirrors and transmits only light of a specific wavelength.
- U.S. Patent 3 shows that by applying a filter, a selective light transmitting sheet with high transmission characteristics in the visible region and high reflection characteristics in the near-infrared region can be obtained. fi 82,528.

Coefficient of 0 or higher and reflectance of approximately 1 ozb, 700 nm
A selective light transmitting laminate having a transmittance of 10 mm or less at 2500 nm and a reflectance of about 90 mm or more has been obtained. In addition, heat-absorbing glass containing Fe oxide, which is known as a selective transmission material that is transparent in the visible light region and absorbs near-infrared light, has a visible light transmittance of 76 cm with a thickness of 5 mm. , solar radiation transmittance coefficient of 57. In addition, in recent years, near-infrared light blue absorption filters (! Samurai Kosho 46-3

C) Problems However, when using FAPRI-BE C-filters for building windows, etc. for energy-saving applications such as blocking solar energy, it is difficult to apply them to large areas, and conventional metal compounds cannot be used as transparent dielectrics. It would be impossible to produce on an industrial scale if
jJ Noh. This means that the technology for uniformly covering a large area of the surface of a metal thin film layer with gold iA rlR compound or the like is still an incomplete technology. If the thickness of the metal oxide film is less than 50A, it is possible to simply form a gold p6 oxide film from the metal film by careful consideration, but as in the present invention, 1, 000
A uniform oxide film with a film thickness of about A over a large area 1 (It can be said that it is impossible to create it in industrial use. In other words, the interlayer film is made of metal ejecta) Suitable for precision optical applications,
It can be said that it is not suitable for Taiyo Kogyo, which is applied in a large area, or for the field of stingray saving and energy saving. In addition, in heat-absorbing glasses, FeO, Fe, and O, which are 442 compounds of F'e, have absorption not only in the near-infrared region but also in the visible region; When the efficiency is improved, the absorption of the light part increases, and the visible light transmittance decreases by 1 level, making it darker and having the disadvantage of coloring the "f" part. This is also seen in the organometallic sardines that have absorption in the near-infrared region, and when Prf, which has an absorption effect in the near-infrared region, is added, the visible light transmittance decreases.・There was a drawback. d) Means to solve the problem We conducted intensive studies to apply a structure with better selective light transmittance to applications such as blocking solar energy, saving energy, and blocking harmful heat rays.As a result, Organic polymer fill, laminated on top of Ag
and a light-selective transmitting structure consisting of a main component and a maple layer, and 8
By optically combining near-infrared light with an absorption peak between 00 nm and 1200 nm and a thin film layer containing a NAN absorber, it is possible to complementarily improve each other's shortcomings.
