上記で得た本発明品1−6及び比較品1−8を用いて作製した偏光板について、それらのゲル分率、ベンゼン環モノマー/TDI系架橋剤の比率、耐久性、光漏れ防止性および塗膜の状態を以下の評価方法で評価した。また、比較品9−11から得られたそれぞれの偏光板の耐久性、光漏れ防止性、および塗膜の状態も同様に評価した。これらの結果を表2にまとめて示す。
得られた粘着剤組成物を乾燥後の厚みが20μmになるように剥離処理したポリエステルの表面に塗布し、乾燥させた後、もう一方の面に剥離処理したポリエステルフィルムを張り合わせて、23℃、50%RHで7日間熟成させて、試験片を作製した。試験片から粘着剤約0.1gをサンプル瓶に採取し、酢酸エチル30ccを加えて24時間振とうした後、該サンプル瓶の内容物を200メッシュのステンレス製金綱でろ別し、金綱上の残留物を100℃で2時間乾燥させて、乾燥重量を測定し、次式より求めた。
ゲル分率(%)=(乾燥重量/採取した粘着剤重量)×100
以下の式により求めた。

得られた粘着剤組成物を乾燥後の厚みが20μmになるように剥離処理したポリエステルフィルムの表面に塗布し、乾燥させた後、もう一方の面にポリエステルフィルムを張り合わせて、23℃、50%RHで7日間熟成させて、試験片を作製した。熟成後の試験片の塗膜の状態を目視で確認した。
偏光フィルムを10cm×10cmの大きさに裁断し、23℃、65%RH条件下に24時間放置した後、その重量を秤量した(これを加熱前重量とする)。次いで、この偏光フィルムを120℃で1時間加熱した後、秤量した(これを加熱後重量とする)。偏光フィルムの水分含有量を下記式によって求めた。
水分含有量(%)=(加熱前重量−加熱後重量)/加熱前重量×100
