Abstract
The present invention is directed to a method for the production of a durably hydrophilic, non-leaching coating. A carbohydrate-salt mixture is formed by at least partially dissolving a water insoluble carbohydrate in an aqueous salt solution to form a carbohydrate-salt complex. The carbohydrate-salt mixture is applied to a substrate, and the substrate is rinsed with a solvent to form a coating.
