ガラス基材の上に硬化性樹脂組成物を50μmのアプリケーターで塗布し、80℃で30分間乾燥させた。メタルハライドランプを用いて1000mJ/cm2の紫外線を照射した後、160℃で1時間加熱して、硬化物をガラス基材から剥離し、硬化物を得た。
硬化物から6mm×40mmの試験片を切り出し、粘弾性測定装置(DMA:レオメトリック社製固体粘弾性測定装置「RSAII」、引張り法:周波数1Hz、昇温速度3℃/分)を用いて、弾性率変化が最大となる(tanδ変化率が最も大きい)温度をガラス転移温度(Tg)とし、以下の基準で耐熱性を評価した。
A:ガラス転移温度(Tg)が130℃以上
B:ガラス転移温度(Tg)が130℃未満
硬化物から10mm×80mmの試験片を切り出し、引っ張り試験装置(島津製作所社製「機密万能試験器オートグラフAG−IS」)を用いて下記条件で伸度を測定し、評価した。
温度23℃、湿度50%、標線間距離20mm、支点間距離20mm、引っ張り速度10mm/分
A:伸度が3.5%以上
B:伸度が3%以上3.5%未満
C:伸度が3%未満
・硬化性樹脂組成物の調製
