Abstract: An anti-fog material comprising a zwitterionic-doped hydrogel made up of charged monomers, at least a portion of which comprise zwitterionic monomers, uncharged hydrophilic monomers, and at least one crosslinking agent is disclosed. A composition for forming the hydrogel and a transparent, removable article comprising the anti-fog material are also disclosed. The article, which may be in the form of a film or decal, may comprise an active layer attached to a backing layer, the active layer comprising an anti-fog material described herein. A method of making a surface of a substrate resistant to fogging by applying the transparent and removable article thereto is also disclosed.

Abstract: An anti-fog coating composition to form a crosslinked film comprising a prepolymer and at least one amine bearing crosslinker is disclosed. The prepolymer comprises one or more charged monomer residues, one or more hydrophilic uncharged monomer residues, and one or more amine reactive monomer residues. The crosslinked film has a change in haze value of less than 30% when exposed to fog conditions for a period longer than 30 seconds. A kit comprising a first compartment comprising the prepolymer and a second compartment comprising the amine bearing crosslinker is also disclosed. The anti-fog film and a coated article comprising the anti-fog coating are also described herein. A method of making anti-fog coated substrate by applying the composition thereto is also disclosed.
