    摘要： Described is a process for producing adherent layer(s) on organic polymeric substrates following the steps of (a) treating the surface of the polymeric substrate to provide reactive groups; (b) applying to the surface a polymerizable composition of organic anhydrides, isocyanates and/or a mixture thereof that is substantially free of organosiloxanes; and (c) curing the polymerizable coating. Further steps include applying an additional layer which is substantially free of organosiloxanes and that may or may not contain the polymerizable composition of the present invention. Also described are products produced by the process that may be transparent, tinted, tinted and polarized or photochromic.

    摘要： An optical article that includes an optical element and an anisotropic coating layer formed over at least a portion of the optical element. The anisotropic coating layer can include a first light-influencing zone comprising at least one first anisotropic material and a second light-influencing zone comprising at least one second anisotropic material. The at least one of the first light-influencing zone and the second light-influencing zone further include at least one dichroic material and/or at least one photochromic-dichroic material such that the first light-influencing zone and the second light-influencing zone exhibit a different color property, a different photochromic-dichroic reversible change, a different amount of polarization, or a combination thereof.
