摘要： A method of preparing a shaped article having a photochromic coating thereon, and curable photochromic powder coating compositions are described. The method includes: applying at least one curable powder coating composition to at least a portion of the interior of a mold, e.g., a lens mold, wherein at least one of the applied powder coating compositions includes a photochromic amount of photochromic material; curing at least partially the applied photochromic powder coating; charging a polymerizable organic casting composition into the mold; polymerizing the casting composition; and removing a shaped article having a photochromic coating on at least a portion of its surface from the mold.
