Abstract
Description
(1)カルボキシル基を有する水分散性ウレタン樹脂100重量部と、水溶性カルボジイミド化合物1〜25重量部と、水分散性カルボジイミド化合物1〜25重量部と、を含有する易接着組成物が提供される。
(2)前記水溶性カルボジイミド化合物と前記水分散性カルボジイミド化合物との重量比が30:70〜95:5の範囲である、(1)記載の易接着組成物;
(3)前記水分散性ウレタン樹脂100重量部に対し、さらに、微粒子を0.1〜15重量部含有する、(1)又は(2)記載の易接着組成物;
(4)熱可塑性樹脂フィルムと、該熱可塑性樹脂フィルムの少なくとも一方の表面に設けられ、且つ(1)〜(3)のいずれか記載の易接着組成物から形成される易接着層とを備える光学フィルム;
(5)前記熱可塑性樹脂フィルムは、(メタ)アクリル系樹脂からなる(4)記載の光学フィルム;及び
(6)偏光子と、該偏光子の表面を被覆して保護する(4)又は(5)記載の光学フィルムとを備える偏光板;を提供する。
(7)水系溶媒で希釈され、カルボキシル基を有する水分散性ウレタン樹脂100重量部と、水溶性カルボジイミド化合物1〜25重量部と、水分散性カルボジイミド化合物1〜25重量部と、を含有する易接着組成物を、熱可塑性樹脂フィルムの少なくとも一方の表面に塗布して塗膜を形成する工程と、前記塗膜を乾燥して易接着層を形成する工程からなる光学フィルムの製造方法を提供する。
本発明の易接着組成物は、カルボキシル基を有する水分散性ウレタン樹脂(以下単にU樹脂と呼ぶことがある)と、架橋剤として水溶性カルボジイミド化合物(以下単にS化合物と呼ぶことがある)及び水分散性カルボジイミド化合物(以下単にD化合物と呼ぶことがある)と、を含有する。このように構成された易接着組成物は、高温高湿下での長時間使用における初期性能の低下を抑制するとともに、より過酷な環境下においても密着性に優れる。

1.易接着組成物の製造
表1及び2に示す各成分を、表1及び2に示す固形分量(単位は重量部)となるよう混合し、易接着組成物を製造した。なお、易接着組成物の水系溶媒としてはイオン交換水を使用し、固形分量は8重量%となるよう調製した。
アクリル系樹脂組成物[Tg:135℃、溶融粘度:700Pa・s(温度270℃、せん断速度100(1/sec))]のペレットを、単軸押出機(φ=20.0mm、L/D=25)及びコートハンガータイプTダイ(幅150mm)を用いて280℃で溶融押出し、110℃に保持した冷却ロールに溶融状態の上記樹脂組成物を吐出して、厚さ100μmのアクリル系樹脂フィルムを形成した。次に、アクリル系樹脂フィルムの一方の表面に、上記で得られた易接着組成物を、バーコーターを用いて塗布した後、熱風乾燥機に投入して100℃で90秒間乾燥した。そして、テーブル延伸機を用いて当該フィルムを一軸延伸(延伸倍率:2.5倍)し、厚さ40μmのアクリル系樹脂フィルムの表面に、厚さ0.3μmの易接着層を有する光学フィルムを製造した。
上記で得られた光学フィルムの易接着層側に、ポリビニルアルコール系接着剤組成物を塗布した。また、ケン化処理を施した厚さ40μmのトリアセチルセルロースフィルム(保護フィルム)の片側にポリビニルアルコール系接着剤組成物を塗布した。次に、厚さ30μmの偏光子の両側それぞれに光学フィルム及び保護フィルムをポリビニルアルコール系接着剤塗布層を介して積層し、得られた積層体を熱風乾燥機(70℃)に投入して5分乾燥させて、偏光板を製造した。また、偏光子の両側にトリアセチルセルロースからなる保護フィルムを設けた評価用の基準偏光板を同様に作成した。
(1)初期密着性
上記で得られた偏光板から25mm×250mmの寸法の試験片を切り出し、試験片の光学フィルムの表面に粘着加工を施した後、ガラス板に貼り付け測定用サンプルを得た。その後、サンプルのの偏光子と光学フィルムとの間に切込みを入れ、偏光子と保護フィルムとを掴み、日本接着剤工業規格 JAI 13−1996の浮動ローラー法に準じて、90度での剥離接着強さを測定した。なお、基準偏光板においても同様の条件で剥離接着強さを測定した。測定結果から、剥離接着強さを次の基準により評価した。
○:基準偏光板よりも剥離接着強さが優れるあるいは同等
△:基準偏光板よりも剥離接着強さが劣る
×:密着しておらず測定不可
(2)耐湿熱性(60℃、90%RH)
上記と同様にして得た測定用サンプルを温度60℃、湿度90%RHの恒温恒湿機に入れ、250時間及び500時間放置する熱処理を施した以外は、初期密着性の評価と同様にして、剥離接着強さを測定した。測定結果から剥離接着強さを次の基準により評価した。
◎:基準偏光板よりも剥離接着強さが優れる
○:基準偏光板と剥離接着強さが同等
△:基準偏光板よりも剥離接着強さが劣る
×:密着しておらず測定不可
(3)耐湿熱性(80℃、90%RH)
上記と同様にして得た測定用サンプルを温度80℃、湿度90%RHの恒温恒湿機に入れ、100時間放置する熱処理を施した以外は、初期密着性の評価と同様にして、剥離接着強さを測定した。測定結果から剥離接着強さを次の基準により評価した。
◎:基準偏光板よりも剥離接着強さが優れる
○:基準偏光板と剥離接着強さが同等
△:基準偏光板よりも剥離接着強さが劣る
×:密着しておらず測定不可
