Process for improving adhesion of coatings to polymeric substrates and articles produced thereby

摘要

Describes a process for improving the adhesion of polymeric coatings to organic polymeric substrates and photochromic polymeric substrates. The process comprises irradiating the surface of a polymeric substrate prepared from or coated with a monomer composition having acrylic functionality in an oxygen containing environment with ultraviolet light; etching the treated surface; and applying to the etched surface a polymer- forming coating composition. Further described are articles and photochromic articles comprising in combination a polymeric substrate having on at least one surface thereof an adherent coating or photochromic coating prepared by the aforedescribed process.
