Abstract

Abstract A process is provided for applying printed matter to plastic substrates by coating the substrate with a composition capable of generating aluminum phosphate. A complex aluminum phosphate having at least 1 chemically-bound molecule of an hydroxy compound ROH where R is hydrogen or an organic group is preferred. The coating is heated to provide at least a partially cured layer of aluminum phosphate and the inked pattern is applied thereto.
