Claim:
1. An organometallic layer which is formed from a treatment formulation comprising: (a) an organic polymer containing multi-chelating functionalities, wherein the multi-chelating functionalities are selected from carboxylic, anhydride precursors, or phosphonic acid groups; (b) a metallic agent which is selected from an oxide, hydroxide or salt of silver, copper, nickel, strontium, thallium, tin, titanium, vanadium, zinc, tungsten or zirconium and which forms an organo metallic complex with the organic polymer containing multi-chelating functionalities; and (c) a solvent, wherein the molar ratio (Z:A) of metallic agent (Z) to the chelating functionality (A) of the organic polymer containing multi-chelating functionalities is in the range of 1:1 (Z:A) to 1:10 (Z:A); the treatment formulation having a solid concentration in the range of 1% to 10% based on the total weight of the formulation; and the organometallic layer having a dry thickness in the range of 5 microns or less and being located between a coated substrate and at least one post coating layer of a coating system and capable of being disrupted with an alkaline stripping agent.
