硬化膜の力学的損失係数tanδの値は、動的粘弾性測定によって得られる損失弾性率と貯蔵弾性率との比から容易に求めることができる(JIS K 7244-1)。tanδ値が0.35より低い場合は樹脂の剛性が大きいため、基板へ与える反り量が大きくなり、0.75より高い場合は剛性が小さいため、耐磨耗性が劣る傾向がある。
また、硬化膜のガラス転移点温度は、tanδの値が最大値となる温度から求めることができる。なお、本発明の範囲外である、ガラス転移点温度が10℃より低い場合は樹脂が柔らかくなりすぎるため、耐磨耗性が劣り、65℃より高い場合は樹脂が硬くなりすぎるため、基板へ与える反り量が大きくなる傾向がある。

実施例及び試験例
実施例1~4及び比較例1~3の樹脂組成物につき、構成材料及び使用量と記項目を評価したその結果を表1に示した。なお、記載中の「部」は重量部を示す。
1.銀反射膜基板は、1.1mm厚、直径12cmのブルーレイディスク用のデータが形成されているPC基板に神戸製鋼所社製銀合金GB-100を使用し、平均30nmの膜厚になるようスパッタし、銀反射膜付きディスク基板を作製した。
2.銀反射膜面が上になるようスピンテーブルに乗せ、内径11.5mmまで覆う様に円状のキャップ処理を行い、ついで本発明の紫外線硬化型樹脂組成物を2.5g中心部のキャップ上に供給した。
3.本発明の紫外線硬化型樹脂組成物の粘度に合わせ、1000rpmから1500rpmの速度範囲で4秒から7秒間スピンコートし、各塗布膜厚が95μmから105μmとなるよう塗布した。スピンコート終了間際にキセノンフラッシュランプを2ショット照射し、表面の流動性が無くなる程度に硬化させた。
4.キセノンフラッシュランプを使用し、上側から80Jで8ショット照射して本発明の紫外線硬化型樹脂組成物を完全硬化させ、光透過層を有するブルーレイディスクを得た。
樹脂層の膜厚と反りの数値は、光ディスクの機械特性測定装置であるDr.Schenk社製Prometeus MT-146を用いて行った。反りの値はディスクの外周になるにつれて顕著に差が現れるため、外周端に近い半径58mmの値で評価した。
表中の初期の反り、耐久試験後の反りは下記数式1、数式2により算出した。
(数式1)初期の反り=塗布後の基板の反り-塗布前の基板の反り
(数式2)耐久性試験後の反り=80℃、85%RH、240時間後の塗布基板の反り-塗布前の基板の反り
反りの単位は度で表示。下記基準で判定を行った。
○(良) ・・・初期反り>-0.6 且つ、耐久性試験後の反り量>-0.6
×(不可)・・・初期反り≦-0.6 又は/且つ、耐久性試験後の反り量≦-0.6
耐久性試験としては、前記の工程で作製したブルーレイディスクを80℃、85%RH条件下の恒温恒湿層内に240時間静置し、ブルーレイディスク信号データ測定装置であるパルステック社製ODU-1000を用いて評価を行った。評価判定にはジッターを測定し、下記基準で判定を行った。ジッターはブルーレイディスクの電気信号のひとつであり、これらの数値が高いほどブルーレイディスクの信号データが劣化しており10%以上となるとデータの読み書きが困難となる。
○(良) ・・・ジッター値10%未満。
×(不可)・・・ジッター値10%以上。
耐摩耗性テストとしては、前記の工程で作製したブルーレイディスクの光透過層面を東洋精機製作所製テーバーアブレージョンテスターTS(磨耗輪No.CS-10F)により250g荷重、70rpmの速度で5回転磨耗し、前記耐久性試験と同様にジッターを評価し判定を行った。
○(良) ・・・ジッター値10%未満。
×(不可)・・・ジッター値10%以上。
