らなかった。(Prior art and its problems) In general, when excessive sunlight enters the window of a sunroom, building, house, etc., the contrast between brightness and darkness between the parts of the room that are exposed to light and those that are not illuminated becomes too strong.
The brightness makes it difficult to see and is uncomfortable, and it is also harmful because it causes the room temperature to become higher than necessary and causes fading of furniture and other interior decorations. therefore,
Ideally, the sunlight from the lighting section should enter the room in a soft state. Traditionally, sunshades and blinds have been known as solutions for this purpose. However, these are light blocking means and block most of the light, so
It has the drawbacks of poor light mitigation function and cumbersome operation. Furthermore, since the light shielding means does not have the function of protecting the light-transmitting plate of the lighting section, the light-transmitting plate had to be protected by another means.

容易である。In addition, since the adhesive layer has a light filtering function, when a meshed transparent plate is used as the inner transparent plate, the wire mesh part will not crack due to overheating. Since it is mixed and not formed as an independent single layer, there is no risk of peeling from other layers as would be the case when a single layer is used. Furthermore, since the optical filter resin and the adhesive resin are both made of resin, they are compatible with each other, have good durability, and are easy to manufacture.

例えば次のように混合して用いればよい。The adhesive layer 3 is made by mixing an optical filtering resin with a transparent adhesive resin and, if necessary, adding a colored pigment to the optical filtering resin.As such an optical filtering resin, a mixed alkyd resin is used. For example, these may be mixed and used as follows.
混合アルキド樹脂 ４０％
石油系溶媒 ５０％
紫外線吸収剤 ５％
乾燥剤 ３％
温性良化剤 １％

である。後述のように、５〜１０％の混合比で紫外線を
９９％カットできることが確かめられている。The mixing ratio of the optical filtering resin is preferably 3 to 30%, because if it is less than 3%, the optical filtering function will be reduced, and if it is more than 30%, the adhesiveness will be reduced. As will be described later, it has been confirmed that a mixing ratio of 5 to 10% can block 99% of ultraviolet rays.

て合せ透光板となる。The laminated transparent plate C can be manufactured, for example, by the following steps. First, as shown in FIG. 3(a), a butyl sealing material 5 in the form of a viscous rod containing a thread core is attached to the inner peripheral edge of the outer transparent plate 2 except for the upper part 2a. Furthermore, the same figure (b
), the inner transparent plate 1 is placed on the inside of the outer transparent plate 2, and the two inner and outer transparent plates 1.
The distance between the two transparent plates 1 and 2 to which 2 is fixed is approximately 2 m. As a result, the peripheral edges of the inner and outer transparent plates 1.2 are sealed with the butyl sealing material 5 except for a part 2a. Next, the inner and outer transparent plates 1.2 are tilted as diagonally as possible.
A liquid mixture 7 containing an optical filter resin and a transparent adhesive resin is injected through the injection port defined by the non-sealed portion 2a. After 4 to 6 hours of being allowed to stand, the adhesive layer 3 is semi-cured and the inner and outer transparent plates 1 and 2 are bonded and integrated to form a laminated transparent plate.
上記構造の合せ透光板１．２によれば、接着層３の物理

Ru. Therefore, it is possible to prevent indoor curtains, furniture, carpets, furnishings, etc. from fading due to ultraviolet rays, prevent the indoor temperature from rising due to infrared rays, and reduce glare caused by visible and ultraviolet rays. It can be prevented.
したがって適度な明るさの快適な室内空間を得ることが
