この実施例では、PMMA/酸化ロイコメチレンブルー被覆溶液の調製を記載する。
この実施例では、ポリ(メチルメタクリレート)/酸化ロイコメチレンブルーで被覆したディスクの製造を例示する。実施例1のPMMA/酸化ロイコメチレンブルー被覆溶液約3mLを、スピンコーター上に保持したDVDの内径の周囲にリングとして供給した。600回転/分(rpm)で60秒間スピンコートした後、被膜は不粘着性であり、濃い青色を示した。
dr.shenk PROmeteus測定器(モデルMT−136E)を用いて実施例2のディスクの反射率を測定した。実施例2の手順を用いて複数のディスクを製造し、dr.shenk PROmeteus測定器を用いてこれらの反射率を測定した。初期平均反射率は4.9〜8.3%の範囲内にあった。
試料が地面に対し45°の角度で南を向くようにして、屋外露光用ラックを地面に配置した。試料は、地面から3〜8フィートの範囲内で木材又はポリスチレン上に取り付けた。米国ニューヨーク州スケネクタディで、8月、9月又は10月に試料を露光した。
試料ビーム中には光フィルターを配置し、参照ビーム中には何も配設しないことにより、Unicam UV3 UV/VIS分光計で吸収スペクトルを測定した。
この実施例では、以下の添加剤、即ち4,4’−ビフェノール、ジ−tert−ブチル−4−メチルフェノール(BHT)及び3,5,3’,5’−テトラメチル−4,4’−ビフェノールを含むPMMA/メチレンブルーの1−メトキシ−2−プロパノール溶液(実施例1)について示す結果を得るための実験手順を記載する。
実施例1の溶液15重量部(pbw)を1,2,4−トリヒドロキシベンゼン0.05pbwと混合することで調製した溶液を用い、実施例6と同様にしてサンドイッチディスクを製造した。Daicure SD698を1260rpmで20秒間回転させて接着を行い、次いでDバルブを備えたUVプロセッサー内で21秒間硬化させた。試料の反射率は初期には4.33%であり、キセノンアークウェザロメーター内で20時間露光した後には7.61%であったのに対し、トリヒドロキシベンゼンを用いることなく同様にして製造した対照試料はこの露光後に27.8%の反射率を有していた。トリヒドロキシベンゼンを含まない試料の初期反射率は4.39%であった。
この実施例では、配合染料を含む3種のポリカーボネート組成物から成形した吸光層を用いる耐光漂白性の向上したディスクの製造を例示する。染料含有吸光層の吸収スペクトルを図1に示すが、これらは実施例5の手順を用いて測定した。実施例1の溶液及び実施例2の手順を用いて4つのポリカーボネート製アルミニウム蒸着基板を被覆した。一方の基板の内径上に5mLのDaicure SD698(Dai Nippon社)接着剤を供給し、無色ポリカーボネート層をその上に配置し、1500rpmで20秒間回転させることで「対照」試料を製造した。回転完了の直後、Fusion UV Systems,INC.のUV光装置(1.1J/cm2、1.6W/cm2)を用いてディスクを硬化させた。無色ポリカーボネート層の代わりに染料含有ポリカーボネート吸光層を用いてこの操作を繰り返した。ポリカーボネート中に染料を含む組成物を用いて製造したDVDについて、3日間の屋外日光暴露の前後の反射率測定結果を表2に示す。
実施例6及び8の手順を用い、添加剤を含まないPMMA/酸化ロイコメチレンブルー被膜及び無色ポリカーボネート層を用いて対照ディスクを製造した。同時に、実施例6と同じくPMMA/酸化ロイコメチレンブルー被膜中に4,4’−ビフェノールを用いると共に、染料組成物3のポリカーボネート吸光層を用いてディスクを製造した。実施例4の手順を用いて試料を屋外露光した。このディスクの反射率は初期には4.4%であり、9日間の屋外露光後には5.0%であったのに対し、無色ポリカーボネート層を用いると共に4,4’−ビフェノールを含まない対照ディスクはやはり4.4%の初期反射率を有し、同じ露光後に43.7%の反射率を有していた。
Ineos Acrylics社から入手したElvacite 2010ポリ(メチルメタクリレート)60グラムをボトル内の1−メトキシ−2−プロパノール300グラムに添加し、ローラーミル上で転がして溶解させることで、PMMAの1−メトキシ−2−プロパノール溶液を調製した。溶液をフラスコに移し、溶液の表面上に窒素流(100cc/min)をゆっくりと流しながら約80℃に加熱した。カニューレチューブを用い、脱気した溶液をゴム隔膜で密閉した脱気ボトルに窒素圧によって移した。
実施例10のPMMA/ロイコメチレンブルー被覆溶液約3.5mLを、スピンコーター上に保持したDVDの内径の周囲にリングとして供給し、500rpmで60秒間回転させた。被膜は不粘着性であり、ほとんど無色であった。被膜の厚さは、ディスクの内径から外径にわたって約4〜約5ミクロンの範囲内にあった。しかし、回転中に、「クモの糸」(ポリマーの非常に細いストランド)のかたまりがスピンボウル内に集積した。さらに、長さ約12mm以下のサイズを有する約50本のポリマーストランドがディスクの縁端に付着していた(RD29789による)。
実施例10のPMMA/ロイコメチレンブルー被覆溶液約3mLを、スピンコーター上に保持したDVDの内径の周囲にリングとして供給した。500rpmで60秒間スピンコートした後、被膜は不粘着性であり、ほとんど無色であった。このディスクをDVDプレイヤーに挿入したところ、完全に再生可能であった。
実施例12で得られた被覆ディスクを周囲室内条件下で放置し、その間にdr.shenk PROmeteus測定器(モデルMT−136E)を用いて様々な時点で平均%反射率を測定した。%反射率が低下するのに伴い、ディスクの色はほとんど無色から青色に変わった。結果を図2に示す。ディスクを空気中に約1週間置いた後、ディスクは濃い青色となってDVDプレイヤーで再生されなかった。
実施例1の溶液を用い、スピンコーターにより800rpmで60秒間回転させることで、0.6ミリメートル(mm)の非金属蒸着ポリカーボネートからなる第一の基板にPMMA/ロイコメチレンブルーベースコートを塗布した。平均被膜厚さは約3ミクロンであることがわかった。PMMA/ロイコメチレンブルーベースコートを有するディスクの一方を窒素室内に一晩保存した後、UV樹脂Daicure SD−640をアルミニウム蒸着した第二の基板の中央に細いリング状に供給した。次いで、PMMA/ロイコメチレンブルーベースコートを有する第一の基板を、UV樹脂のリングを有する第二の基板ディスク上に結合した。このサンドイッチを1000rpmで10秒間回転させることでUV接着剤を均一に分散させた。次いで、サンドイッチをフラッシュキセノンUVランプの下方を25秒間通過させた。次いで、サンドイッチを窒素室内に48時間以上保存した。
実施例14と同様にして溶液を調製した。この溶液を用い、スピンコーターにより800rpmで60秒間回転させることで、0.6mmのアルミニウム蒸着ポリカーボネートからなる第一の基板にPMMA/ロイコメチレンブルーベースコートを塗布した。平均被膜厚さは約3ミクロンであることがわかった。PMMA/ロイコメチレンブルーベースコートを有する第一の基板を窒素室内に一晩保存した後、UV樹脂Daicure SD−640を以前に金属蒸着した第一の基板の中央に細いリング状に供給した。次いで、非金属蒸着ポリカーボネートからなる第二の基板を、UV樹脂のリングを有する第一の基板上に配置した。このサンドイッチを1000rpmで10秒間回転させることでUV接着剤を均一に分散させた。次いで、サンドイッチをフラッシュキセノンUVランプの下方を25秒間通過させた。次いで、サンドイッチを窒素室内に48時間以上保存した。
組成物A、B、C及びDをブレンドし、次いで一軸押出機を用いて290℃の溶融温度で押し出してペレット化した。ペレット化した材料を120℃のオーブン内で4時間乾燥した後、該材料で基板(0.6mmハーフディスク)を成形した。成形操作のためには、Seiko Geikin DVD金型を備えたSumitomo SD30成形機を使用した。
