Abstract
The present invention provides a process for providing on the surface of a substrate an adherent phorphorous acid-based coating layer, the method comprising contacting said surface with a carrier conveying a coating composition comprising an acid selected from the group consisting of phosphoroic acids, organo-phosphoric acids, phosphonic acids, and mixtures thereof, at a sufficient temperature and for a sufficient time to bond at least a portion of the acid in the compositon to the oxide surface.
Claims5
A coated article formed by:
- a) depositing a metal oxide surface layer on a polymeric substrate;
- b) depositing an organophosphorous acid compound on said oxide surface layer;
- and
- c) exposing the substrate of (b) to a temperature sufficient to bond the acid functional group of said organophosphorous acid compound to said oxide surface layer of (b) on said substrate of (a).
