本発明は偏光ガラスの改良に関するものである。より詳

問題があった。即ち、明るい色を有して見通しが良く、
かつ色彩を自由に選択し得る偏光ガラスの出現が強く望
まれていた。Conventionally, polarizing glass, polarizing filters for cameras, etc. are known as products using polarizing glass. However, the tints of these conventional polarizing glasses are extremely dark and limited, and it is not possible to freely select a favorite tint. When such polarized glass is used for car window glass, etc., there is a problem that although there is little problem in bright daylight, visibility becomes extremely poor when it is dark outside, such as at dusk or at night. . Further, when ski sunglasses are made of polarized glass, there is a problem in that the unevenness of the snow surface is difficult to distinguish due to the dark color. In other words, it has a bright color and has good visibility.
In addition, there has been a strong desire for the emergence of polarizing glass that allows the user to freely select colors.
本発明者は、視野が明るく、乱反射光による眩惑を防ぐ
ことができ、かつ種々の色彩に見える偏光ガラスを得ん
と鋭意努力した結果、２枚の一軸延伸フイルムが形成す
る角度を変えて、フィルムを透過する光を偏光ガラスに
より見た場合に、色彩が色々に変化することを見出して
本発明をなすに至った。As a result of our earnest efforts to create a polarized glass that has a bright field of view, can prevent dazzling from diffusely reflected light, and can appear in a variety of colors, the inventor of the present invention discovered that by changing the angle formed by two uniaxially stretched films, The present invention was developed based on the discovery that when light transmitted through a film is viewed through polarizing glass, the color changes in various ways.
即ち、本発明は、偏光ガラスの偏光面に２枚以上の一軸
延伸フィルムを貼り合わせて成る偏光ガラスを提供する
ものである。That is, the present invention provides a polarizing glass made by laminating two or more uniaxially stretched films to the polarizing plane of the polarizing glass.
本発明において、偏光ガラスとしては、ガラス製、結晶
石製、プラスチック製のもの等、一般に偏光ガラスと呼
ばれているものを使用し得る。また、偏光ガラスは一枚
に限られず、必要に応じて二枚以上何枚をも貼り合わせ
て用いることができる。In the present invention, as the polarizing glass, it is possible to use what is generally called polarizing glass, such as glass, crystal stone, plastic, and the like. Further, the number of polarizing glasses is not limited to one, and two or more sheets can be bonded together as needed.
次に、本発明で用いる一軸延伸フィルムとしては、−軸
延伸により作られ、適度の透明度を有するものであれば
何でも使用できる。Next, as the uniaxially stretched film used in the present invention, any film can be used as long as it is made by -axial stretching and has appropriate transparency.
当該フィルムの厚さは特に制限されないが、加工に際し
耐え得る適度の強度を有することが必要である。かかる
−軸延伸フィルムの例として、セロハン、ポリエチレン

湿セロハンを用いるのが好ましい。本発明において、−
軸延伸フィルムを２枚以上使用する必要があるが、この
場合、同種類のフィルムを用いてもよく、異る種類のフ
ィルムを用いてもよい。The thickness of the film is not particularly limited, but it is necessary to have an appropriate strength that can withstand processing. Examples of such axially stretched films include cellophane, polyethylene, and polypropylene films, and even those called sheets may be used as long as they do not impair the purpose of the present invention. When using cellophane, it is preferable to use moisture-proof cellophane from the viewpoint of moisture resistance. In the present invention, -
Although it is necessary to use two or more axially stretched films, in this case, the same type of films or different types of films may be used.
本発明の偏光ガラスは、偏光面に一軸延伸フイルムを貼
り合わせることにより作られる。The polarized glass of the present invention is produced by laminating a uniaxially stretched film on a polarizing surface.
−軸延伸フィルムは偏光ガラスの一万の面にのみ順次重
ねて貼り合わせてもよく１、両方の面にそれぞれ貼り合
わせてもよい。また、二枚以上の偏光ガラスを用いる際
、ガラスとガラスとの間に一軸延伸フイルムを挾んで全
体を形成してもよい（−例を第２図に示す）。- The axially stretched film may be laminated onto only the 10,000 sides of the polarizing glass one after another, 1 or may be laminated onto both sides, respectively. Furthermore, when using two or more sheets of polarizing glass, a uniaxially stretched film may be sandwiched between the glasses to form the whole (an example is shown in FIG. 2).
この場合、偏光面に対してフィルム同志が作る角度θ（
第１図参照）が極めて重要となる。In this case, the angle θ(
(see Figure 1) is extremely important.
この角度θを変えることにより通る光を種々の色に変更

最も好ましい。By changing this angle θ, the passing light can be changed into various colors. For example, it can produce various colors that cannot be seen in conventional polarizing glasses, such as red-based colors such as orange, blue-based colors, green-based colors, and gray. Furthermore, surprisingly 2
When two films were placed at an angle of 90° (i.e., θ=90'), the transmitted light was brighter than when one film was used. This phenomenon is extremely noticeable when a combination of polyethylene film and polypropylene film is used as the hafilm, and therefore, the combination of polyethylene film and polypropylene film is most preferred.
偏光ガラスに一軸延伸フイルムを貼り合わせる方法は、
特に制限されず、熱による接着方法、接着剤を用いる方
法等を使用することができる。この場合フィルムの透明
性を損なわない適当の温度、透明な接着剤を選ぶことが
必要である。本発明において真空接着法が好ましい。The method of laminating uniaxially stretched film to polarized glass is as follows:
There are no particular limitations, and methods such as thermal adhesion, methods using adhesives, etc. can be used. In this case, it is necessary to select an appropriate temperature and transparent adhesive that does not impair the transparency of the film. In the present invention, a vacuum bonding method is preferred.

窓ガラスに使用し得ることも言うまでもない。The polarizing glass of the present invention constructed as described above allows the light passing therethrough to be made into a desired color. Furthermore, when used in window glasses of automobiles, it is possible to prevent dazzling caused by diffusely reflected light, and the field of view is bright and does not deteriorate visibility even at dusk or at night. Furthermore, when used as sunglasses for skiing or fishing, it prevents dazzling from diffusely reflected light from the snow or water surface, allows you to clearly see the unevenness of the snow surface, and allows you to clearly see the movement of floats floating in the waves. It goes without saying that it can also be used for window glass in houses, etc.
