Zusammenfassung:	To provide a method of making optical articles having gradient light-influencing properties.SOLUTION: A method of making an optical article having a gradient tint and a gradient polarization includes bringing one or more dye compositions including at least one of a dichroic dye, a photochromic-dichroic dye or any combination thereof into contact with an optical element having a continuous coating including at least one alignment zone. At least a portion of the dye composition diffuses into the coating at a predetermined concentration gradient along at least a portion of the coating.SELECTED DRAWING: None 【課題】勾配のある光影響特性を有する光学的物品の製造方法を提供する。【解決手段】勾配のある色合いおよび勾配のある偏光を有する光学的物品を製造する方法であって、二色性染料、フォトクロミック二色性染料またはこれらの任意の組合せの少なくとも１つを含む１種または複数の染料組成物を、少なくとも１個のアラインメントゾーンを含む連続コーティングを有する光学要素と接触させることを含み、染料組成物の少なくとも一部が、コーティングの少なくとも一部に沿った所定の濃度勾配でコーティング中に拡散する、方法。【選択図】なし
