前記実施例1〜実施例5及び比較例1〜比較例4で製造した組成物を洗浄されたLCDガラス基材上に硬化後に、厚さが2μmになるように、インクジェットコーティング方法でコーティングした。異物の付着を防止するために、コーティング後、1分以内にコーティング層を下記の条件で紫外線を照射して硬化することにより、ベゼルパターンを形成した。紫外線照射器は、高圧水銀灯を使用し、UV基準1000mJ/cm2の光量で照射した。
ディスプレイパネル(以下、パネル)の上部面に、前記製造例1の方法によってベゼルパターンを形成し、上部基材としてアクリル系粘着層を使用するLG化学製造のNRT偏光フィルムを付着した。付着後には、偏光フィルムとパターンとの隙間に水分及び異物の混入を防止するために、シーラントで周囲をインキャップした。
前記実施例1〜実施例5及び比較例1〜比較例4で製造した組成物に対して粘度を測定した。粘度測定装備としてBrookfield社のViscometer DV−2を使用した。
前記各組成物を温度35℃の対流オーブンに一定時間備え付けて、組成物の蒸発速度を観察した。蒸発速度の定義は、各組成物をアルミニウム皿にマイクロ秤を用いて1g重量ほど入れた後、対流オーブン内で時間が経過した後に残った組成物の重量を測定して、初期に比べて、残留物の比として計算した。前記測定結果を下記表2に示し、蒸発開始後、2時間が経過した後、残余質量の比率が85%以上であれば、○で示し、85%未満の場合、結果Xで示す。
前記各組成物を実験用インクジェットプリンター(UJ−200、ユニジェット)を用いて1分間連続して吐き出した後、15分間吐出を中止して、休止時間を有することにより、ノズルの乾燥が起こるようにした後、再び紙上に吐出を実施した。各組成物の吐出が円滑になされるかを評価した。前記測定結果を下記表2に示し、紙上にインクが正常に吐き出されて正常な印刷物が出力された場合、結果を○で示し、インクの乾燥による吐出不良が発生して、印刷物の品質が低下した場合、結果をXで示した。
前記各組成物をガラス基板にスポイトで塗布し、1000〜5000rpmの回転速度でスピンコーティングを実施した。その後、UV照射装置(高圧水銀灯、Innocure 5000、第一UV)を用いて総露光量が1000mJ/cm2の紫外線を照射して、組成物を硬化させた。露光量の測定は、UV puck 2(EIT社)測定器を用いて行った。前記測定結果を下記表2に示し、照射後に、1分経過後、指触した時、液膜が完全に硬化されず、液体が付いて出る時は、Xに示し、液膜が完全に硬化されず、べたつきが残っている場合には、△、薄膜が完全に硬化されてべたつきがなかった場合には、○で示した。
製造例1の方法でインクジェットコーティングの代わりに、スピンコーティングで一般LCDガラス基材上に厚さが1μmになるように、コーティングした組成物の光学密度/厚さをX−rite社のOD測定器を用いて測定した。測定した値は、表2に記入した。
