Abstract:
The present invention relates to compounds represented by the following Formula (II), Ring-A of Formula II can be, for example, an aryl group, and Q′ and Q′″ can each be independently selected from groups, such as, halogen, —OH, —CN, amine groups, amide groups, carboxylic acid ester groups, carboxylic acid groups, alkenyl groups, alkynyl groups, carbonate groups, sulfide groups, and sulfonic acid ester groups. The present invention also relates to photochromic compositions and photochromic articles that include one or more photochromic compounds such as represented by Formula II.
