縦横25mm、厚さ0.7mmのガラス板に膜厚15nmのITO膜が幅2mmのパターンで形成されたガラス基板(旭硝子(株)製)上に、正孔注入材料としてポリ(3,4)エチレンジオキシチオフェン/ポリスチレンサルフォネイト(PEDOT/PSS)を含有する正孔注入層形成用塗液を3000rpmで50秒間スピンコートを行い、膜厚50nmの正孔注入層を形成した後、高純度窒素中、200℃で10分間加熱・乾燥を行った。ここで、正孔注入層形成用塗液としては、PEDOT/PSSを純水に固形分0.1質量%で溶解したものを用いた。正孔注入層上に、発光材料ポリフルオレン誘導体の1.0質量%溶液を2000rpmで50秒間スピンコートを行い、膜厚70nmの有機発光層を形成した後、60℃で10分間焼成した。有機発光層上に、10-5Paの圧力条件下、0.1nm/secの蒸着速度でLiFを10nm、0.1nm/secの蒸着速度でCaを20nm積層し、その上に20nm/secの蒸着速度でAlを100nm積層して陰極を形成した。
上記調製した実施例1~実施例44および比較例1~6の各水分捕獲体形成組成物の製膜性、各水分捕獲体の耐熱性、ガラス密着性、発光外観および光取出し効率を下記方法に従い評価した。その評価結果を表1、表2および表3に合わせて示す。
上記調製した各水分捕獲体形成組成物を用い、長辺66mm、短辺24mm、厚さ1.1mmのガラス基板に、長辺58mm、短辺13mm、深さ0.3mmの掘込みを設け、この堀込みに水分捕獲体形成組成物200μLを塗布した後、高圧水銀ランプを用いてUV照射(照射エネルギー:1J/cm2)により硬化させて水分捕獲体を形成し、目視により外観観察を行った。このとき、クラックおよび凹凸が認められない場合、製膜性は良好「○」と、クラックまたは凹凸の少なくともいずれかが認められた場合、不良「×」と評価した。
サンプル管中に、上記調製した各水分捕獲体形成組成物を適量入れ、上述の[製膜性]の硬化条件と同じ条件で、膜厚2mmの水分捕獲体をサンプル管底部に形成した。次いで、形成した水分捕獲体を大気に暴露して十分吸湿させた後、サンプル管の蓋を閉めてシールし、サンプル管の底部が上(製膜面が上)となるように固定した状態で85℃の環境下に静置した。その後、336時間経過した時点の水分捕獲体の状態を観察した。このとき、水分捕獲体に全く変化が認められなかった場合、耐熱性は極良好「○」と評価し、極軽微な変化のみが認められた場合、良好「△」と評価し、水分捕獲体が下方へ垂れて変形が認められた場合、不良「×」と評価した。
上記調製した各水分捕獲体形成組成物を用い、長辺66mm、短辺24mm、厚さ1.1mmのガラス基板に、上述の[製膜性]の硬化条件と同じ条件で、膜厚2mmの水分捕獲体を形成した。大気中における、上記ガラス基板からの各水分捕獲体の剥離の有無を観察した。このとき、剥離が認められない場合、密着性は良好「○」と、剥離した場合、不良「×」と評価した。
上記[有機EL素子の製造]で得られたそれぞれの有機EL素子について、室温において順方向電流を10mA/cm2通電し、発光外観(ダークスポット、ムラ)を観察した。また、コニカミノルタセンシング(株)社製分光放射輝度計「CS-2000」により正面輝度を測定し、光散乱層を形成していない基板で作製した有機EL素子の正面輝度を基準とし、白色発光素子の正面輝度の向上率を算出した。

ダークスポット、ムラが観察されない:良(○)、
ダークスポット、ムラが観察される:不可(×)
・光取出し効率
正面輝度向上率1.2倍以上:優(◎)、
