<p>PROBLEM TO BE SOLVED: To provide a photochromic material having improved compatibility with a composition in which the photochromic material may be incorporated, for example, a coating composition (urethane coating composition or the like).SOLUTION: The present invention relates to a photochromic material that includes a photochromic compound that includes a photochromic substituent (e.g., an indeno-fused naphthopyran) and at least one pendent silane group bonded to the photochromic substituent. The pendent silane group is selected from certain pendent siloxy-silane groups and/or pendent alkoxy-silane groups represented by general formulas (I) and/or (II) as described in further detail in the specification. The present invention also relates to a photochromic article including the photochromic material of the present invention (such as a photochromic optical element (e.g., a photochromic lens) and a photochromic coating composition (e.g., a curable photochromic coating composition)).</p> |
