Description
・400〜460nm、好ましくは420〜450nmの範囲内の波長を有する光を少なくとも部分的に阻止する少なくとも1種の染料Aと、
・染料Aにより透明光学物品に付与された色のバランスを少なくとも部分的に調整するための少なくとも1種の蛍光増白剤Bであって、前記少なくとも1種の蛍光増白剤Bが400〜460nm、好ましくは420〜450nmの範囲内の波長の光を蛍光により発し、且つ前記染料A及び前記蛍光増白剤Bが互いに異なる、蛍光増白剤Bと、
を含む透明光学物品を提供する。
I.有機溶媒性及び/又は水性の高温着色浴、好ましくは水性溶液中に基材を数分間浸漬することによる含浸方法又は浸染方法。
有機レンズ基材等の有機材料から作製された基材は、ほとんどの場合、90℃程度の温度に加熱された且つ染料が分散された水性着色浴中に浸漬することにより材料のバルク中で着色される。染料は、こうして基材の表面下に拡散し、色濃度は、基材の本体中に拡散する染料の量を調整することにより得られる。
II.含浸可能な一時的コーティングを必要とする特開2000−314088号公報及び特開2000−241601号公報に記載の拡散方法。又は
III.米国特許第6534443号明細書及び米国特許第6554873号明細書に記載されるように昇華性材料を用いた無接触着色。又は
IV.基材自体の製造時、例えば、をキャスト又は射出成形することによる青色吸収色素の組込み。
i)以下の構造を有してEastobrite(登録商標)OB−1という商品名でEastman Chemical社により市販されている2,2’−(1,2−エチレンジイルジ−4,1−フェニレン)ビスベンゾキサゾール
