Abstract:
1. A composition comprising: (a) a hydrophilic polymer comprising a polyvinylpyridine hydrophilic polymer and a chlorite anion; (b) a hydrophobic polymer comprising carboxylate substituted hydrophobic polymer; and (c) a silver ion present at a level of 0.01% to 9.9% by weight, wherein the silver ion is associated with a pyridine group of said polyvinylpyridine hydrophilic polymer and a negatively charged carboyxlate group of said carboxylate substituted hydrophobic polymer so as to form a molecular bridge between the hydrophilic polymer and the hydrophobic polymer; and wherein said chlorite anion oxidizes any silver metal formed from said silver ion to inhibit formation of silver metal clusters.
