Further, there were problems in that the number of parts increased, the optical adhesion precision and the adhesion process increased, and the cost increased. - On the other hand, in the method of depositing a multilayer film for infrared rays protection on a quartz plate, - it is necessary to accurately control the film thickness for each layer, and the number of laminated layers is also 30 or more, so it is a large-scale process. There were problems with this, such as the need for expensive equipment and the unavoidable occurrence of defects such as pinholes, which resulted in a higher defect rate than color correction glass and a significant increase in production costs.

調整に当たっては、−たん近赤外線吸収剤を塩化メチレ
ンに溶解させた後、三本ロールを用い均一に混合させた
後、塩化メチレンを飛散させ、近赤外線吸収剤の分散を
十分に行うことが望ましい。In preparing the one-component near-infrared absorbing adhesive in one embodiment of the present invention, the -tan near-infrared absorbing agent was dissolved in methylene chloride, mixed uniformly using a three-roll roll, and then dissolved in methylene chloride. It is desirable to disperse the near-infrared absorbent sufficiently.
まず、各成分の量をかえた時の接着強度についてその結
果を第１表に示す。First, Table 1 shows the results regarding the adhesive strength when the amounts of each component were changed.
尚、ここで示している接着強度とは、ガラス基板（材質
ＢＫ−７）上に接着剤を筺布し、水晶の試験片（３ｉｎ
Ｘ ３ ｍｍ Ｘ ２ ＋ａ ）を乗せ、一定荷重で
加圧し、ガラス面から紫外線（ＵＶ）照射により接着を
行った後、横方向からプッシュプルゲージで押圧し、水
晶試験片を剥離させ、その剪断剥離強度を測定したもの
である。第２表かられかるように、Ｍ３の配合量により
調整を行った接着剤が最も強い接着強度を有していた。The adhesive strength shown here refers to the adhesive strength applied to a glass substrate (material BK-7) and a crystal test piece (3 inch
x 3 mm x 2 + a), pressurized with a constant load, and bonded by irradiating ultraviolet (UV) light from the glass surface, then pressed from the side with a push-pull gauge to peel off the crystal specimen and shear it. Peel strength was measured. As can be seen from Table 2, the adhesive adjusted by adjusting the blending amount of M3 had the strongest adhesive strength.
これは、可撓性付与剤に含まれるヒドロキシル基による
水晶板との水素結合の数が増加したことによる影響であ
ると考えられる。しかしながら、可撓性付与剤の配合量
が多すぎると、接着強度が弱くなるのは、光重合開始剤
濃度が低くなり、十分な硬化反応を促進することができ
なくなり、硬化した樹脂そのものの強度が低下したため
であると考えられる。This is thought to be due to an increase in the number of hydrogen bonds with the quartz plate due to the hydroxyl groups contained in the flexibility-imparting agent. However, if the amount of flexibility imparting agent is too large, the adhesive strength will be weakened because the photopolymerization initiator concentration will be low and the curing reaction will not be able to be promoted sufficiently, resulting in the strength of the cured resin itself. This is thought to be due to a decrease in
次にぬ３の組成をもとに、近赤外線吸収剤の分散性と、
硬化性についてその結果を第２表に示す。Based on the composition of 3 below, the dispersibility of the near-infrared absorber,
The results regarding curability are shown in Table 2.
尚、近赤外線吸収剤の分散性をよくするために、塩化メ
チレンに溶解させた後、配合組成Ｎｎ３に配合した。In order to improve the dispersibility of the near-infrared absorber, it was dissolved in methylene chloride and then blended into composition Nn3.
また、近赤外線吸収剤としては、ＨＲ−１１゛と５ＩＲ
−１２８を用い、その配合比率は常に２：１の割合で配
