Title:
反応性置換基を有するフォトクロミック物質
Document Type and Number:
Japanese Patent JP4950176
Kind Code:
B2
Abstract:
Various non-limiting embodiments of the present disclosure relate to photochromic materials comprising a reactive substituent. For example, the present disclosure contemplates photochromic materials, such as photochromic naphthopyrans and indeno-fused naphthopyrans having a reactive substituent comprising a reactive moiety linked to the photochromic naphthopyran by one or more linking groups. In certain non-limiting embodiments, the reactive moiety comprises a polymerizable moiety. In other non-limiting embodiments, the reactive moiety comprises a nucleophilic moiety or an electrophilic moiety. Other non-limiting embodiments of the present disclosure relate to photochromic articles, compositions, and methods of making the photochromic articles, wherein the photochromic articles and compositions comprise the photochromic naphthopyrans described herein.
