Interlaminar grafting of coatings, particularly grafting of a lubricious outer coating upon an anchor coating supported upon glass or plastic, for example, to provide anti-fogging or lubricating characteristics. The method is characterized by its ability to anchor permanently the highly lubricious coating to the glass or plastic.

Method of interlaminar grafting of coatings

Plastics, particularly a method of hydrophilic coating of plastics, for example, a contact lens, with a lubricating and visually acute mucopolysaccharide film which is immobilized upon the surface of the plastic for the lifetime of the plastic. A preferred method includes first coating the plastic with an aqueous solution of a mucopolysaccharide, drying by applying a water-miscible solvent, then crosslinking and permanently immobilizing the first coating upon the plastic by applying a solution of catalyzed organic solution aliphatic polyisocyanates.
