ABSTRACT:
An anti-fog liquid coating composition comprises: a polymer which is polyvinylpyrrolidone, polydimethylacrylamide or a polyvinylpyrrolidone copolymer with a polymerizable alpha olefin free of functional groups reactive with isocyanates; a polyisocyanate prepolymer; a surfactant which will chemically bond to a reaction product of the polymer and prepolymer, and an organic solvent to form a solution of the foregoing ingredients.
The invention includes a substrate having an anti-fog transparent coating comprising the reaction product of polyvinylpyrrolidione, a polyvinylpyrrolidone copolymer with a polymerizable alpha olefin free of functional groups reactive with isocyanates or polydimethylacrylamide with a polyisocyanate prepolymer, said reaction product being chemically bound to a surfactant.
On curing, the surfactant is chemically combined with the hydrophilic polymer/isocyanate prepolymer composition and is not subject to extraction in any significant amount while still conferring improved fog resistance to the coated substrate.
