    摘要： 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., a transparent substrate such as a glass or organic polymeric substrate, as for example, a thermoset or thermoplastic substrate, (2) a photochromic polymeric coating appended to at least a portion of at least one surface of the substrate, the photochromic polymeric coating containing a photochromic amount of at least one organic photochromic material, e.g., spirooxazine, naphthopyran, diarylethene and/or fulgide, and (3) a thermally cured transparent thermoset polymeric coating superposed on, e.g., coherently appended to, the photochromic coating, the thermally cured polymeric coating being harder than the photochromic polymeric coating. Describes also the aforedescribed photochromic article having an abrasion-resistant coating affixed to the thermally cured polymer coating, e.g., an abrasion-resistant coating comprising an organo silane; and a photochromic article having an antireflective coating affixed to the abrasion-resistant coating.

    摘要： Described is a coating composition adapted to enhance the adhesion of a polymeric coating or film applied to a substrate. The coating composition is interposed between the substrate and the polymeric coating and comprises (a) at least one coupling agent, partial hydrolysates thereof or mixtures thereof in a concentration greater than 25 weight percent, based on the weight of the total composition, and (b) an adhesion enhancing amount of an epoxy-containing material having at least two epoxy groups. The coating composition is substantially free of photochromic materials and colloidal particles chosen from silica, alumina or mixtures thereof. Also described is a process for using the coating composition and articles coated with the composition and additional coatings and films which can be photochromic.

    摘要： The present invention is directed to a method of preparing a phenolic foam that has cell walls which are substantially free of perforations. The method comprises using certain anhydrous aryl sulfonic acids as the foaming and curing catalysts. The useful anhydrous aryl sulfonic acids are those which have a pKa of less than about 2.0 and which change the compatibility of the phenolic resole with water. The preferred anhydrous aryl sulfonic acid is a combination of toluene sulfonic acid and xylene sulfonic acid. The invention is also directed to a phenolic foam having cell walls which are substantially free of perforations and to foamable phenolic resole compositions for preparing the phenolic foam.

    摘要： Coating compositions are disclosed that include an alkoxide and a silica sol that includes silica nanoparticles and a polymerizable (meth)acrylate binding agent. The polymerizable (meth)acrylate binding agent remains substantially uncrosslinked after the coating composition has been cured to form a hard coat. Also disclosed are articles at least partially coated with a hard coat deposited from such a coating composition, methods for depositing a hard coat on at least a portion of a plastic substrate, and methods for improving the adhesion and abrasion resistance of a coating composition.
