Abstract
Hydrophilic coating of plastics, particularly an enhanced aqueous solution of a polysaccharide which flows uniformly over the surface of an anchor film applied to the plastic. The aqueous solution of a polysaccharide from the group consisting of hyaluronic acid and its salts, chondroitin sulfate and agarose is enhanced by the addition of albumin to provide uniform wetting over the anchor film on the plastic.
