ABSTRACT:
This invention relates to a plastic substrate having on its surface an adherent photo-product coating, and a method for coating that substrate, which coating is formed by exposing to light in the presence of an oxygen source, a reactant mixture comprising: 2,2'4,4'-tetrahydroxybenzophenone, with (1) ammonium hydroxide and optionally a trace amount of at least one reactive metal, or (2) ammonium hydroxide and at least one metal salt, or (3) at least one metal salt and at least one amine, or (4) ammonium hydroxide, at least one metal salt and at least one amine; in a suitable solvent.
