Described are novel photochromic polymerizable polyalkoxylated 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 polyalkoxylated substituent of from 1 to 50 alkoxy units per substituent which is end-capped with a polymerizable group. Specific substituents are also present on the naphtho, indeno and pyrano portions of the compounds. These compounds may be represented by the following graphic formulae: ##STR1## Also described are various substrates, e.g., paper, glass, polymeric organic materials, etc., 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, e.g., certain other naphthopyrans, indenonaphthopyrans, benzopyrans, oxazine-type compounds, etc., are also described.
本文描述了新型光致变色可聚合聚烷氧基萘并吡喃化合物,其中的例子包括至少含有1至50个烷氧基取代基的某些2H-萘并[1,2-b]吡喃、3H-萘并[2,1-b]吡喃和吲哚并[2,1-f]萘并[1,2-b]吡喃化合物,并且这些取代基被聚合物化基团端封。这些化合物的萘、吲哚和吡喃部分上也存在特定的取代基。这些化合物可以用以下化学式表示:##STR1## 此外,本文还描述了各种基材,如纸张、玻璃、聚合有机材料等,这些基材含有或被涂覆上述化合物。本文还描述了包含新型萘并吡喃化合物或与互补光致变色化合物(如某些其他萘并吡喃、吲哚并萘并、苯并吡喃、噁唑型化合物等)组合的光学透明制品,例如隐形眼镜或其他塑料透明物。
