Abstract: The invention provides a method for the at least partial removal of one or more polymeric coating layers from a coated substrate having at least one coated surface. The method includes generating at least one reactive species in an ionized gas stream discharged at atmospheric pressure; and placing the coated surface in the ionized gas stream. The at least one reactive species reacts with the one or more polymeric coating layers such that one or more coating layers is at least partially removed from the coated surface of the substrate at atmospheric pressure.

Abstract: Describes a photochromic article, e.g., an ophthalmic photochromic article, such as a plastic lens, in which the article includes (1) a rigid substrate, such as a transparent thermoset or thermoplastic polymeric 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 photochromic material, e.g., spirooxazine, naphthopyran and/or fulgide, and (3) a layer chosen from a second organic polymeric coating or an abrasion resistant coating that is superposed on said photochromic polymeric coating. Describes incorporating at least one polysiloxane surface active agent within the photochromic polymeric coating in amounts sufficient to inhibit migration of the photochromic material, e.g., into said layer superposed on said photochromic polymeric coating.

Abstract: A curable film-forming composition is provided that on curing produces a coating, comprising in a medium (i) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) 20 to 85 percent by volume based on the total volume of the film-forming composition of particles having a mean particle size less than 100 nm. The particles further have an index of refraction sufficiently similar to that of the polymer of (ii) to minimize haze, and have an affinity for the medium sufficient to keep the particles suspended therein. The affinity of the particles for the medium is greater than the affinity of the particles for each other, thereby preventing agglomeration of the particles within the medium.
