<フォトクロミック組成物(重合性組成物)の調製>
プラスチック製容器内で、(メタ)アクリレートの合計100質量部に対して、68質量部のポリエチレングリコールジアクリレート、12質量部のトリメチロールプロパントリメタクリレート、20質量部のネオペンチルグリコールジメタクリレートを混合し、(メタ)アクリレート混合物を調製した。この(メタ)アクリレート混合物100質量部に対して、2.5質量部となるようにフォトクロミック化合物を混合した。更に、光重合開始剤(フェニルビス(2,4,6-トリメチルベンゾイル)ホスフィンオキシド)、酸化防止剤[ビス(3-tert-ブチル-4-ヒドロキシ-5-メチルフェニル)プロピオン酸)][エチレンビス(オキシエチレン)及び光安定化剤(セバシン酸ビス(1,2,2,6,6-ペンタメチル-4-ピペリジル))を混合し、十分に攪拌した後、シランカップリング剤(γ-メタクリロキシプロピルトリメトキシシラン)を攪拌しながら滴下した。その後、自動公転方式攪拌脱泡装置で脱泡した。
以上の方法により、フォトクロミック組成物を調製した。
プラスチックレンズ基材(HOYA社製商品名EYAS:中心厚2.5mm、直径75mm、球面レンズ度数-4.00)を濃度10質量%の水酸化ナトリウム水溶液(液温60℃)に5分間浸漬処理することでアルカリ洗浄し、更に純水で洗浄し乾燥させた。その後、このプラスチックレンズ基材の凸面に対して、水系ポリウレタン樹脂液(ポリカーボネートポリオール系ポリウレタンエマルジョン、粘度100cPs、固形分濃度38質量%)を室温且つ相対湿度40~60%の環境において、ミカサ社製スピンコーターMS-B150を用い、回転数1500rpmで1分間スピンコート法により塗布した後、15分間自然乾燥させることにより、厚さ5.5μmのプライマー層を形成した。
上記で調製したフォトクロミック組成物を、上記プライマー層の上に滴下し、ミカサ社製MS-B150を用い、回転数500rpmから1500rpmまで1分間かけてスロープモードで回転数を変化させ、更に1500rpmで5秒間回転させるプログラムを用いたスピンコート法により塗布した。その後、プラスチックレンズ基材上に形成されたプライマー層上に塗布された上記フォトクロミック組成物に対し、窒素雰囲気中(酸素濃度500ppm以下)で紫外線(主波長405nm)を40秒間照射し、この組成物を硬化させてフォトクロミック層を形成した。形成されたフォトクロミック層の厚さは45μmであった。
こうして、フォトクロミック物品(眼鏡レンズ)を作製した。
<着色濃度の評価>
JIS T7333:2005に準じた以下の方法によって視感透過率を求めた。
実施例及び比較例の各眼鏡レンズの凸面に向けて、キセノンランプを光源に用いてエアロマスフィルターを介した光を15分間照射し、フォトクロミック層を着色させた。この照射光はJIS T7333:2005に規定されているように放射照度及び放射照度の許容差が表1に示す値となるように行った。この着色時の透過率を大塚電子製分光光度計により測定した。波長範囲380nmから780nmの範囲での測定結果から求めた視感透過率T(%)を表2に示す。T(%)の値が小さいほど、フォトクロミック化合物が高濃度に着色していることを意味する。
退色速度は以下の方法により評価した。
実施例及び比較例の各眼鏡レンズの光照射前(未着色状態)の透過率(測定波長:550nm)を大塚電子製分光光度計により測定した。ここで測定された透過率を「初期透過率」と呼ぶ。
各眼鏡レンズに対し、キセノンランプを光源に用いてエアロマスフィルターを介した光を15分間照射し、フォトクロミック層を着色させた。この照射光はJIS T7333:2005に規定されているように放射照度及び放射照度の許容差が表2に示す値となるように行った。この着色時の透過率を初期透過率と同様に測定した。ここで測定された透過率を「着色時透過率」と呼ぶ。
その後、光照射を止めた時間から透過率が、[(初期透過率-着色時透過率)/2]となるまでに要する時間を測定した。この時間を「半減時間」とする。半減時間が短いほど退色速度が速いということができる。求められた半減時間を表2に示す。
