上記各成分を、後記の表1〜表4に示す割合で配合した後、加熱溶融混合することにより、実施例および比較例の光硬化型樹脂組成物を調製した。なお、比較例1は、実施例1と対比するために設けたものであり、後記の表1および表3に示すように、比較例1における各成分の配合組成は、オキセタン化合物の種類が異なること以外は、実施例1と同じである。後記の表1〜表4に示すように、他の比較例も、その番号と同じ番号の実施例と対比するために設けたものである。
光硬化型樹脂組成物(液状樹脂)を1×1.5×0.5cmの透明成型型に流し込み、UVを16000mJ照射し硬化させた後、型から外し150℃で1時間の加熱処理を行った。このようにして得られた成形物(硬化物)の表面を、グラインダーにより研磨し、屈折率計(アタゴ社製)を用いて、上記成形物(硬化物)の25℃での屈折率を測定した。
光源に水銀ランプ(浜松ホトニクス社製、LC−8、365nmでの照度が30mW/cm2になるよう設定)を用いたUVレオメーター(Rheologica社製、15mmφのアルミ製パラレルプレート使用)によるゲルタイムを測定し、硬化性の評価を行った。上記UVレオメーターによるゲルタイムは、上記各光硬化型樹脂組成物の粘弾性を25℃で測定した際の弾性項(G′)の105Pa到達時間とした。
5gに計量した光硬化型樹脂組成物(液状樹脂)をアルミシャーレにとり、これを、25℃,60%の恒温恒湿槽に入れて30分間放置した。そして、恒温恒湿槽に入れる前(槽投入前)と、恒温恒湿槽に入れて放置した後(槽放置後)との樹脂組成物中の水分量(含有率)を、カールフィッシャー容量滴定方式自動水分量測定装置(KF−07型、三菱化学社製)により測定した。また、この測定値より、恒温恒湿槽に放置したことによる水分量増加率(吸水率)を算出した。
