ABSTRACT:
Described is a process for producing an adherent organic polymeric layer on organic polymeric substrates following the steps of (a) treating the surface of the polymeric substrate to provide reactive groups; (b) applying to the treated surface a polymerizable composition of a surface modifying amount of an organofunctional silane, a catalyzing amount of material which generates acid upon exposure to actinic radiation, and a solvating amount of solvent; (c) exposing the coated surface to an adhesion improving amount of actinic radiation; and (d) applying and curing a photochromic or non-photochromic polymer-forming composition on the coated surface. Also described are articles produced by the process.
