測定結果及び評価を下記第2表-1、第2表-2に示す。
2mm角のシリコンチップのミラー面に、硬化性組成物1~22のそれぞれを厚さが約2μmになるよう塗布し、塗布面を被着体(銀メッキ銅板)の上に載せ圧着した。その後、180℃で2時間加熱処理して硬化させて試験片付被着体を得た。この試験片付被着体を、予め所定温度(23℃、100℃)に加熱したボンドテスター(シリーズ4000、デイジ社製)の測定ステージ上に30秒間放置し、被着体から50μmの高さの位置より、スピード200μm/sで接着面に対し水平方法(せん断方向)に応力をかけ、23℃及び100℃における、試験片と被着体との接着力(N/2mm□)を測定した。
接着力試験において、100℃における接着力が、23℃における接着力の65%以上である場合を「○」、65%未満である場合を「×」と評価した。
硬化性組成物1~22のそれぞれを、長さ25mm、幅20mm、厚さ1mmとなるように鋳型に流し込み、140℃で6時間加熱して硬化させ、試験片をそれぞれ作製した。得られた試験片につき、分光光度計(MPC-3100、島津製作所社製)にて、波長400nm、450nmの初期透過率(%)を測定した。
初期透過率測定において、400nmの透過率が80%以上を「○」、70%以上80%未満を「△」、70%未満を「×」と評価した。
初期透過率を測定した各試験片を150℃のオーブンに500時間投入し、再度、波長400nm、450nmの透過率(%)を測定した。これを加熱後透過率とした。
加熱後透過率測定において、400nmの透過率が、初期透過率の80%以上であれば「○」、70%以上80%未満であれば「△」、70%未満であれば「×」と評価した。
