    • Described are polymeric matrix compatibilized naphthopyran compounds, examples of which are certain 2H-naphtho[1,2-b]pyrans, 3H-naphtho[2,1-b]pyrans and indeno[2,1-f]naphtho[1,2-b]pyrans each having at least one substituent containing terminal and/or pendant groups selected from hydroxyl, carboxyl, sulfo, sulfono, (meth)acryloxy, 2-(methacryloxy)ethylcarbamyl, epoxy or a mixture thereof. Specific substituents are also present on the naphtho, indeno and/or pyrano portions of the compounds. These compounds may be represented by the following graphic formulae: Also described are various substrates that contain or that are coated with such compounds. Optically clear articles such as contact lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, are also described.
    • 描述的是聚合物基质相容的萘并吡喃化合物,其实例是一定的2H-萘并[1,2-b]吡喃,3H-萘并[2,1-b]吡喃和茚并[2,1-f]萘并[1,2 (甲基丙烯酰氧基)乙基氨基甲酰基,环氧基或它们的混合物中的至少一个含有末端和/或侧基的取代基的-b]吡喃各自具有选自羟基,羧基,磺基,磺基,(甲基)丙烯酰氧基, 具体的取代基也存在于化合物的萘酚,茚并和/或吡喃葡萄糖部分上。 这些化合物可以由以下图形表示:还描述了含有这些化合物或者被这些化合物包被的各种底物。 还描述了光学清洁的物品,例如隐形眼镜或其它掺入新型萘并吡喃化合物或其组合与互补光致变色化合物的塑料透明胶片。
