Abstract
A water-based coating composition suitable for preparing hydrophilic surfaces on various articles is provided which includes a supporting polymer having functional moieties capable of undergoing crosslinking reactions, said supporting polymer soluble in or emulsified in an aqueous based medium; and a hydrophilic polymer, said hydrophilic polymer associated with the supporting polymer. The composition is characterized in that, when crosslinked at the functional moieties, the supporting polymer forms a three-dimensional network which substantially minimizes disassociation of the hydrophilic polymer.
