Abstract

The present invention is directed to an anti-fogging coating that can be used for anti-fog applications. The coating is transparent, and comprises a hydroxyl group containing polymer, an aluminum containing crosslinker, and a surface active agent containing hydroxyl and/or siloxane groups. Additionally, the coatings possess a T.sub.fog of greater than about 30 minutes and a haze of less than about 5%, and can advantageously be used to provide to glass or plastic substrates an anti-fogging surface.
