Patent ID: 7879456

Claim:
A method of bonding an adherent phosphorous-containing coating layer to an oxide surface on a substrate, wherein said substrate with an oxide surface is selected from the group consisting of: (a) oxidized iron, titanium, silicon, tin and vanadium; (b) indium tin oxide; and (c) substrates with oxide layers deposited thereon, wherein said substrates on which said oxide layers are deposited are selected from the group consisting of ceramics, semiconductors, metals, plastics and glass, said method comprising: (i) adsorbing or absorbing onto a hydrophilic carrier a solution comprising a coating composition comprising an organophosphonic acid compound, (ii) contacting said oxide surface with said carrier conveying said coating composition, and (iii) heating said oxide surface and carrier at a sufficient temperature while maintaining contact for a sufficient time to bond a layer of said organophosphonic acid compound to said oxide surface, wherein said adherent phosphorus-containing coating layer comprises said organophosphonic acid compound in an amount up to about 10 times greater than the amount in a coated article comprising the same substrate and oxide surface that is treated directly with said solution comprising said coating composition.
