Claim:
A method of protecting a silver film deposited on a substrate to prevent the silver film from delaminating, comprising the steps of: a) preparing a paint base by mixing a first cross linkable resin selected from the group consisting of: alkyd, polyester, acrylic, epoxy and epoxy modified acrylic resins, a second cross linking resin selected from the group consisting of: melamine-formaldehyde, urea-formaldehyde, isocyanates and amine resins, a modifying resin selected from the group consisting of epoxy and phenoxy resins and a metal carboxylate selected from the group consisting of: octoates, tallates, rosinates, laurates, oleates, octadecanoates, neodecanoates, linoleates, naphthenoates, versatates and hexanoates; b) applying the paint base to the silver film; c) curing the paint base with heat to cross link the resins; and d) contributing metal II ions from the selected metal carboxylate to the cured paint to thereby prevent the silver film from delaminating.
