<p>Primer compositions for adhering overcoatings derived from in situ polymerizations of uncured monomers onto inorganic substrates. These primer compositions when coated on a substrate and included in a layered structure comprise at least one non-amino- or non-amido-containing silane, at least one of certain metal esters, and preferably an acidic material. The overcoatings are derived from epoxy and vinyl monomers which require a superior level of adhesion. The primed and overcoated substrates of the present invention provide articles having protective or decorative surface layers.</p> |
