選択的に遮断しうる安全ガラスに関する。DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to safety glass with selective light transmission. More specifically, it relates to safety glass that can selectively block ultraviolet and near-infrared rays without losing transparency.

を通して窓から太陽光が入射すると紫外光による家具。b. Prior Art Conventionally, glass plates have been produced by laminating one or more glass plates onto a plasticized polyvinyl butyral resin sheet. i
Composite glass, so-called laminated glass, is widely known, which is designed to prevent fragments from scattering even if exposed to 1Hjm. The furniture is exposed to ultraviolet light when sunlight enters the window through the laminated glass.
カーペット等の日焼を起し、又自動車の窓に使った場合
は内装材の劣化、退色を起していた。It causes sunburn on carpets, etc., and when used on car windows, it causes deterioration and discoloration of interior materials.
一方近赤外光の入射は＠に夏場人体Ｋ“はてり感”を与
え、冷房費を増大させ、さらには自動車の運転者及び同
乗車の不快感を増大せしめていた。On the other hand, the incidence of near-infrared light gives the human body a ``swelling'' feeling in the summer, increases cooling costs, and further increases the discomfort of the driver and passengers in the car.
Ｃ１問題点
この為通常、熱線吸収ガラスが用いられていたが、とれ
は近赤外光は遮断出来るが、紫外線の遮断は不可前であ
り、しかもガラスにＦ＠ の如き熱線吸収剤を安定に配
合しなければならないため、値段が高く々す、例えば自
動車では高級車の窓に使用されているＫすぎない。C1 Problem: For this reason, heat-absorbing glass was usually used, but although it can block near-infrared light, it is impossible to block ultraviolet rays, and moreover, it is difficult to stabilize heat-absorbing agents such as F@ into the glass. Because it has to be blended, it is expensive. For example, in automobiles, K is used in the windows of luxury cars.
更に近年色付きのフィルムが市販され、建物窓や自動車
窓にはりつけて、主として外からの透視性防止と云う目
的で使われてきた。Furthermore, in recent years, colored films have become commercially available and have been used primarily to prevent visibility from the outside by pasting them onto building windows and automobile windows.

ある。However, it has the disadvantage that the transmittance in the visible region is low and it is dark for general use. In other words, JI
There is a S regulation, and the permeation through the frame is required to be 70 inches or more, and surface abrasion resistance is also required, making this film unsuitable.

該フィルムを挿入する事は、特殊な技術が必要である。Furthermore, in recent years, it has been proposed to insert a film with added functionality between the interlayer films of laminated glass to block the Tai 1 field energy (see Japanese Patent Laid-Open No. 56-32352). but,
Inserting the film requires special techniques.

。That is, UV transmittance (300-449 mμ): 10 cm or less, visible light transmittance (450-700 mμ) near 0 cm or more, near-infrared transmittance (701-2100 mμ) = 50 cm or less, ultraviolet transmittance exceeding 10%. This increases the risk of sunburn and interior material deterioration due to sunlight passing through the laminated glass. If the visible light transmittance (450-700-) is less than 70 inches, it will not meet the standards (JIS R-3211) for laminated glass for automobiles. The visible light transmittance is more preferably 72 inches or more, most preferably 75 inches or more. If the near-infrared transmittance (701 to 2100 mμ) exceeds 50 inches, the so-called near-infrared rays will pass through well, so the temperature reduction effect will be reduced.

Harm from sunlight, i.e. deterioration of interior materials due to ultraviolet rays,
Furthermore, it is possible to suppress the temperature rise inside the vehicle due to near-infrared rays. This is because cars, etc. are traveling at high speed, so the energy absorbed by the transparent laminate is transmitted to the outside.
This is because almost no signal is transmitted inside the car.
