ABSTRACT:
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.
