Describes a photochromic article, e.g., an ophthalmic photochromic plastic article, such as a lens, in which the article includes (1) a rigid substrate, e.g., polymeric substrate, such as a thermoset or thermoplastic substrate, (2) a photochromic polymeric coating appended to at least one surface of the substrate, the photochromic polymeric coating containing a photochromic amount of at least one photochromic material, e.g., spirooxazine, naphthopyran and/or fulgide, and (3) a film comprising a maleimide derivative coherently appended to the photochromic coating. Describes also the aforedescribed photochromic article having an abrasion-resistant coating affixed to the maleimide derivative-containing film, e.g., an abrasion-resistant coating comprising an organo silane; and describes further a photochromic article having an antireflective coating affixed to the abrasion-resistant coating.
描述了一种光致变色制品,例如眼科光致变色塑料制品,如镜片,其中该制品包括(1)硬质基材,例如热固性或热塑性基材;(2)附着在基材至少一个表面上的光致变色聚合物涂层,该光致变色聚合物涂层包含光致变色基材,如热固性或热塑性基材、聚合基底,例如热固性或热塑性基底;(2) 附着在基底至少一个表面上的光致变色聚合涂层,该光致变色聚合涂层含有至少一种光致变色材料的光致变色量,例如螺螨嗪、萘并吡喃和/或富勒烯;(3) 包含马来酰亚胺衍生物的薄膜,该马来酰亚胺衍生物相干地附着在光致变色涂层上。还描述了前述光致变色制品,该制品具有贴在含马来酰亚胺衍生物薄膜上的耐磨涂层,例如由有机硅烷组成的耐磨涂层;并进一步描述了光致变色制品,该制品具有贴在耐磨涂层上的抗反射涂层。
