光硬化性固着剤には、貯蔵安定性向上のため重合禁止剤(E)を添加することができる。重合禁止剤としては、メチルハイドロキノン、ハイドロキノン、2,2-メチレン-ビス(4-メチル-6-ターシャリーブチルフェノール)、カテコール、ハイドロキノンモノメチルエーテル、モノターシャリーブチルハイドロキノン、2,5-ジターシャリーブチルハイドロキノン、p-ベンゾキノン、2,5-ジフェニル-p-ベンゾキノン、2,5-ジターシャリーブチル-p-ベンゾキノン、ピクリン酸、クエン酸、フェノチアジン、ターシャリーブチルカテコール、2-ブチル-4-ヒドロキシアニソール及び2,6-ジターシャリーブチル-p-クレゾール等が挙げられる。
重合禁止剤(E)の使用量は、(A)及び(B)の合計量100質量部に対して、0.001~3質量部が好ましく、0.01~2質量部がより好ましい。0.001質量部以上であれば、貯蔵安定性が確保されるし、3質量部以下であれば、良好な接着性が得られ、未硬化になることもない。
照射する光の照射量は、365nmの受光器を使用した積算照度計で測定して、一般に30~4000mJ/cm2、典型的には100~3000mJ/cm2であり、より典型的には300~2500mJ/cm2、好ましくは1000~2000mJ/cm2である。照射時間としては一般に0.1~120秒、典型的には1~30秒、より典型的には10~20秒程度である。光の照射を貼り合わせの圧力を維持したまま実行することで、硬化歪みを抑えて固着剤の厚みを制御し、透光性硬質基板の積層精度を高めることができる。
